Okay so I used struggle too. I think it's always easier to think of fractions as a cake or pizza
So basically if It say I took 1/4 of pizza
I'm pizza terms in would mean there was 4 slices and I took 1 leaving 3/4.
If like I said there was 3/8 of pizza left there was originally 8 slices and only 3 left now
Hope this helps you
