9/10 greater than 6/8

Yes.

First, you find the fractions with common denominators: 9/10 is equal to 72/80 and 6/8 is equal to 60/80.

Since 72 is greater than 60, 9/10 is greater than 6/8.

Yup!
You can also use a calculator to slove this-
Change them to percents.
9/10 s 90%, then 6/8 would be 75%, since 6 divided by 8 is 0.75, and 0.75x100 is 75. So 75%!
90% is bigger than 75%, so you are absolutely right!
