You can put this solution on YOUR website! Leila is on her way home in her car. She has driven 20 miles so far, which is four-fifths of the way home.
What is the total length of her drive?
:
let d = total distance of the drive
:
four-fifth of the total distance = 20 mi d = 20
get rid of the denominator, multiply by 5, results
4d = 5(20)
4d = 100
d = 100/4
d = 25 miles is the total length
:
Prove this to yourself, take 4/5 of 25
