Question

Kade makes 5/6 cup salad dressing. He uses 2/3 cup dressing on a salad. How much salad dressing is left

Answer 1

To solve
`(5)/(6) - (2)/(3)`, we need to find a common denominator. If we multiply
`(2)/(3)` by
`(2)/(2)`, we get
`(4)/(6)`. The reason we can do this is because two over two is really just equivalent to 1, and multiplying a number times one equals the original number. So if you're subtracting
`(4)/(6)` from
`(5)/(6)`, you have



`(5)/(6) - (4)/(6) = (5-4)/(6) = (1)/(6) \ cups`.
