1 - 3/8 - 1/8 = ____


For the above type of math questions, will marks be deducted if the child did not reduce the answer to ‘1/2’ after getting ‘4/8’?
Thanks.

no marks should be deducted unless the question specifies that answer must be in the simplest form.

However, as a good habit, teach the child to reduce at all times especially simple fractions like 4/8

Adrian & Zen shared some marbles equally. After Zen received 58 marbles from Adrian, how many more marbles than Adrian did Zen have?


The answer is 116 marbles??

I can’t figure out why?

let me try huh..but I don't know how to show it here by model so below is my explanation:

Adrain has A + 58 marbles
Zen has A + 58 marbles also
So when Zen received 58 marbles from Adrain then
Zen would have A + 58 +58 = A + 116 marbles
and Adrain would have A marbles
so Zen has 116 marbles more then Adrain!

Hope my explanation is correct

Initially,
A[====]
Z[====]

After giving
A[==]-58
Z[====]==]+58

hence 58+58=116.

sorry, i'm not so good at using this platform to illustrate models.
