Adult here, going back in time to make sure my KS2 Maths is perfect before I teach myself GCSE and A Level Maths. Hopefully will eventually complete BEng Electrical in 6-7 years from now

This is the only question I got wrong when I took some old sats papers.

Here's what I did:

Changed 2 / 5 to 4 / 10.

So I have to find 4 sets of numbers that make another number.

The mark scheme is saying one of the acceptable answers is 50. I don't see how this can be?

What are the factors of 50?
5 * 10
10 * 5

It says I can only use numbers between 1 and 10

Just realized my stupid mistake haha.

Factors of 50: 1, 2, 5, 10 == 4/10
