Question

A parking lot is 100 yards long . what is the length of 3/4 of the parking lot , in feet ?

Answer 1

100 yards
3/4 of 100=3/4 times 100=300/4=75
1y=3f so therefor 3f/1y=1
convert 75y to f
75y/1 times 3f/1y=225f since the units cancel

the answe ris 225 feet

Answer 2

3/4 of the lot is 3/4*100=75 yards long.  This is 75*3=225 feet.
