His mom paid 30 and he paid 10 I did 40÷4 the got 10 then times by how many 25% each had
You solve it like an equation and then you operate on both sides to keep equallity
You can find an equivalent fraction for any fraction by multimplying both the top and the bottom numbers by the same numbers.
For example, I'll use 10.
1(10)/10(10)=10/100
So, 10/100 is an equivalent fraction of 1/10.
Hope this helps!
