**There were 70 runners to start a race.**

In the first half of the race, 1/5 of them dropped out.

In the second half of the race, 4/7 of the remaining runners dropped out.

How many runners finished the race?

**Answer**

Hey there!

So,to do this, I would recommend making the fractions into decimals.

1/5 is equal to 0.2 so you multiply that times 70 runners .

This equals 14 runners who dropped out.

Subtract those who dropped out from the total and now you have 56 runners left.

4/7 as a decimal is about 0.575.

Times that by 56 and you get another 32 who dropped out.

You're now down to only 24 runners who finished the race.
