Question

A cook has 1 2/3 cups of flour. A recipe calls for 1 1/2 cups of flour. Does the cook have enough flour? If not, how much more flour is needed?

Answer 1

The cook has enough flour.

Explanation:

When working with mixed fractions, I would always make the denominator the same before comparing. Since the lowest common multiple between 3 and 2 is 6, I will change both fractions to a denominator of 6.

Cook has 1
`(2)/(3)` = 1
`(4)/(6)`

Recipe needs 1
`(1)/(2)` = 1
`(3)/(6)`

Since the cook has
`(1)/(6)` more than what the recipe needs, the cook has enough flour.
