Question

How do you know 72/80 is greater than 7/8? Explain.

Answer 1

Because 7/8 is the same as 70/80 and 72 is greater than 70 so yeah.

Answer 2

Question: How do you know
`(72)/(80) \ \textgreater \ (7)/(8) ?`

To know for sure why its larger, you need to make sure they have the same denominator (bottom number)

To do that, multiply both sides in
`(7)/(8)` by 10 which is
`(70)/(80)`


`72\ \textgreater \ 70`
