Answer 1

The story problem that represents 1/2 ÷ 2/5 is about John eating part of a pizza and asks how much is left. To solve this, multiply the fractions and find that 1/5 of the pizza is left.

Step-by-step explanation:

The story problem that represents the division problem 1/2 ÷ 2/5 is option B: John has 1/2 of a pizza, and he ate 2/5 of it. The question asks how much is left.

To solve this, we can multiply the fraction 2/5 by the fraction 1/2. When multiplying fractions, we multiply the numerators together and the denominators together. So, 2/5 multiplied by 1/2 is (2*1)/(5*2) which equals 2/10.

Therefore, there is 2/10 or 1/5 of the pizza left.
