Afootball team spent 1/10 of its pratice stretching the next 2/5 running positions drills and another 7/20 running team drills. the remaning time was spent on sprint. what fraction of the total time was spent running sprint?

First, we need to convert all these into the x/20 fraction. Multiply 1/10 by 2/2, and get 2/20, and 2/5 by 4.

Our new fractions are:
2/20
8/20
7/20
If we add all these together, we get 17/20.
The remaining time is 20/20 minus 17/20, which gives us 3/20.
3/20ths were used for sprinting.

Omg that is a big question and weird words and i’m only 5
