City workers are paving a street that is 1 1/2 miles long. if they repave 1/4 mile per day, how long will it take to repave the entire street?

The question is to find out how many times 1/4 is equal to 1 1/2

First lets convert the total:

1 1/2 = 2/2 + 1/2 = 3/2

now we need to find out a number that multiplied by 1/4 gives 3/2, that is an equation:

(1/4) x = 3/2

and solving for x:

x = (3/2) * 4

x = 12/2

x = 6

therefore they will take 6 days to repave the whole street
