Question

A recipe calles for 4/5 cup of sugar and 1/3 of cinnamon. How much more sugar is needed than cinnamon.

Answer 1

Before you can compare, you need to find common denominators. The common denominator of
`(4)/(5)` and
`(2)/(3)` is 15. So the fractions are now:
`(12)/(15)` and
`(5)/(15)`. Then subtract to find the difference:

`(12)/(15) - (5)/(15) = (7)/(15)` more cups of sugar are needed.

Hope that helps.

Answer 2

to find the difference you would need to make the denominator equal so I changed it to 15 and the difference would be 7/15
