How do you use equivalent fractions to compare the fractions in each pair

4/5 and 9/10

And 2/3 and 5/8

Firstly you need to to reduce to a common denominator by multiplYing the whole fraction. This way you have to multiply 4/5 by 2 (both numerator and denominator). so 4/5 = 8/10. And now you have 8/10 and 9/10. You compare only numerators. This way you have 8/10 15/24.
