The answer is just 8.

Unless I'm not understanding the question properly?

I thought that however dd seems to have an longwinded way of having to show working out.
Eg. 6/15 =
6 - 3x2 = 2
15 - 5x3 =5

So the answer is 3/5

Maybe it's the fact that the question involves bigger numbers that's frazzled her :/

Start really simply? What the question is asking is essentially, how many times does 37 go into 296, with the possibility of there being a remainder. Add 37 to 37, then add another 37... Stop when the last 37 you add takes you over 296 - or in this case, when you get to 296, as it is a multiple of 37.

Or am I missing something as well?

It looks like they are being expected to break down the numbers into their prime factors.

37 is a prime number so you are looking to break down the numerator:

296 = 2 x 148 = 2 x 2 x 74 = 2 x 2 x 2 x 37

Apologies as I clearly haven't explained it very well.
Guest55 - that's exactly what she's been asked to do. She's managed it fine with simpler questions however this one has really thrown her. As her answer she has put
296/37 =38x8 =8
=37x1 = 1
=8

Would the bottom working out be simply 37x1 as 37 is the lowest prime number here?

I think I write the numerator as I did and leave the denominator as 37 is prime.

2 x 2 x 2 x 37
37

Guest55 - May I ask if, in your opinion, this is age appropriate for lower set year 7. Am rather concerned dd is struggling with it so much.

(Guest55, please rescue me here ?) Where does the 38 come from?

Toadmum - I apologise, that was a typing error on my part & should have read 37 as opposed to 38. Sorry for any confusion, it really has been one of those days!
