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.
