Challenge Number 3: Can you use inverse operations to solve this problem?

Emily chooses two numbers.
She addes the two numbers together and divides the result by 2.
Her answer is 44.
One of Emily's number is 12.

What is Emily's other number?


Challenge Number 2: Funky Fractions

 This term we have been looking at fractions in Numeracy. To test your knowledge complete this challenge.

 Break a hexagon into 6 equal pieces.
whole hexagon and hexagon cut into 6 equal pieces
What if we just had one of the pieces?
one triangle of hexagon that's cut into 6 equal pieces
That would be 1 piece out of 6 pieces. Right?
Here's how we would write it:
1/6 - the top number is called the numerator and the bottom number is called the denominator
We read this as one sixth.

Now here's your challenge:
Stefan has a bag that contains 3 blue marbles and 5 red marbles only.
What fraction of the marbles in the bag are blue?
Stefan adds one blue marble and one red marble to the bag.
What fraction of the marbles in the bag are blue now?
 


Challenge Number 1: Can you solve this problem?

Amir and Lara went to the market on Electric Avenue to buy some fruit.
Pineapples £1.40 each
     


Peaches £1.99 for a box
Grapes £2.50 for 1kg










Amir buys 2 pineapples and a box of peaches. How much does he pay?

Lara buys half a kilogram of grapes and one pineapple. How much change does she get from £5?

      Well done Tobi. First, good to see you attempted both questions, but can you explain how you solved them?

      Second, a common mistake is to solve only one step in a two or multi-step problem. Take a second look at question 2, how much change did he get from £5?

      Merry Christmas

    1. 1.99
    1.99=3.98

    3.98+
    1.40=5.38

    2. 5.00
    1.50
    1.40= 2.9

    lara gets $2.90 change

      Really good attempts here Kayde. However, you need to be careful when reading the questions and remember to check.

      In question 1 you understood how to solve the problem but you mixed up the items. It read: two pineapples and one box of peaches but you added two boxes of peaches and one pineapple.

      In question 2 again a good understanding, but you need to be careful when finding halves: what is half of £2.50, remember to partition (half of 2, half of .50).

      Finally, how do we calculate the change?

    What up bloogers today we going to try and complete this maths mania.Ok now we have to use the gird method and column method. First we add £1.99p (£2.00p) ok here is the tricky part that sometimes we make mistakes in class 1.99+1.99p= £4.00p that is the answer now that it step 1. Step 2 is adding again. graped+£2.50p+£1.40p=£2.90p.Step 3 is taking away so £5.00p-£2.90p=£2.10p. That is the answer of this question. SO THE MORE WE DO MATHS THE MORE WE WILL GET SMART!!!

    Hi am going to try to complete challenge number 1

    £1.40
    +£1.40
    £2.80
    +£1.99
    =£4.79

    Half of £2.50=£1.25

    £1.40
    +£1.25
    =£2.65

    £5.00
    -£2.65
    =£2.35

    Thanks for listening

    We have been learning about fractions.
    Here is one question 3/4 of 40 =30
    This is how you get the answer, if you ask
    yourself what in the 4 times table makes 40 .....
    it is 10 so do 3 times 10 which gives you .......
    30 so that is your awnswer.

      Well done Omotola! I particularly like the fact that you were able to explain how you worked it out.

      Now try the 'challenge 2' on this page.

    Hi I am going to try to complete Miss Williams challenge of fractions.

    For the first one is 3/8 because if you add 5+3=8 that will give you the answer for the denominator then they are just asking how many marbles are in the Blue bag wich is 3 and thats how I got 3/8.

    For the second one is 4/10 because if you add 6+4=10 that will give you the answer for the denominator then they are asking how many are in the bag of Blue now wich is 4 andn thts how I got 4/10

    Thanks for listening

    hello bloggers i am going to complete challenge 2 of maths mania with fractions.

    For the first question we are trying to find out what fraction of the blue balls are in the bag so here first we would be trying to find the denominator so it says there is 5 red marbles and 3 blue marbles so what method are we going to use basically add so we know that 3+5=8 so now we have got our denominator then now they are asking us what is the fraction of the blue balls which is 3+0=3 so obviously the answer is 3/8.

    Now for the second question,that says that Stefan adds 1 marble for the blue and 1 marble for the red which adds up to 2 so now our number sentence is what is 8+2=10 so now there is 10 marbles in the bag which is our denominator,but we are still trying to find our numerator and it says Stefan adds 1 blue marble so 3+1=4 so we have got our numerator so our answer is 4/8.

    Thank you for reading.

    hello bloggers i want to correct my mistake our answer for question 2 is 4/10

    ReplyDelete
  20. dontai23 January 2013 at 21:10

    First one is that Stefan has 3 marbles in the blue bag and 5 marbles in the red bag 3/3 and 5/5.3+5=8 3+0=3 so the answer is 3/8.

    The second one is Stefan adds 1 marble to each marble bag so that means it adds up to 2 marbles which adds the denominator 8+2=10. Then the numerator adds 1 blue marble which is 3+1=4 so we have our answer is 4/10.

    Hello bloggers,i am going to be trying to solve challenge 3. So, Emily chooses two numbers.
    She addes the two numbers together and divides the result by 2.
    Her answer is 44.
    One of Emily's number is 12.

    What is Emily's other number?

    Well i have worked out what Emily`s numbers are 12 and 76. The way i worked that out because if it say you add the two number then divide then u get 44 and one of ur answers is 12. Then you would have to investigate what can you at to twelve to get double of 44 and it was 76.

    Thank you for reading.

    miss willimas question was emily has a number the dives it by 2,then gets 12 what is the answer?
    it could be 36 because 36+12=48

  26. Ridwaan21 February 2013 at 20:40

    I think the answer is 32 because 32+12=44.

    ReplyDelete
  27. Ridwaan21 February 2013 at 21:32

    44X2=88 88-12=76

    The answer is 76 because I did the inverse operation to solve the problem to get my answer. Emily used division and addition and I used the inverse which is times and subtraction.
