Question

Round each fraction to the nearest half to find the estimate. There is eight tenths of a cake and Riley eats six tenths of it. Estimate how much cake is left. Explain your thinking.

Answer 1

2/10 or 1/5

Explanation:

8/10-6/10=2/10

If fractions have the same number on the bottom, you can subtract or add the top numbers. The bottom number does not change during this process.

Answer 2

2/10 or 1/5

Explanation:

take 6 away from 8 and you get 2. That is your numerator. If you had 10 to begin with, that is your denominator so it will look like 2/1. IF SIMPLIFIED IT IS 1/5.
