What fraction is shaded?

I was looking to review the mocks with year 11 and decided instead of working through each paper, I’d work through by related topics.

I noticed Ss in my class had trouble with finding of amounts when you ended up with parts. They also didn’t notice things in diagrams like 3.5 shades out of 7 is a half or 3.5 out of 14 is a quarter. They didn’t seem comfortable with decimals in fractions

I hope students are able to find the fractions shaded in the images below
