A regulation football field is 120 yd long, including the two end zones. Each end zone is 10 yd long. What fraction of the football field is made up of the two end zones?

So the end zones are 10

there are 2 end zones so 2 times 10 = 20

20 yards are taken up by endzones

20/120 yards is endzone

solve/simplify

find the ones EXG. so 4/8 can be simplified to 1/2 because 1/2 times 4/4=4/8

so 20/120=2/12 times 10/10

2/12=1/6 times 2/2

the end zones take up 1/6 of the filed

If the total length is 120 yards, and there are two end-zones of 10 yards each, the expression 10 (2) / 120 or, 20 out of 120 yards, can give the fraction 1/6. This is your answer.
