Question

Katie needs 3/4 cup of sugar to make cookies. She only has 1/3 cup. How much more sugar does Katie need?​

Answer 1

`(5)/(12)` cups

Explanation:

This question is asking for the difference between the two values so subtraction is necessary

`(3)/(4) -(1)/(3)`

Multiply the top and bottom of the first fraction by 3 and the second one by 4
`(3*3)/(4*3) -(1*4)/(3*4) = (9)/(12) -(4)/(12)`

Now just substract

9 - 4 = 5 ==>
`(9)/(12) -(4)/(12) = (5)/(12)`
