The main road in Belleville is 7 3/10 Miles long so far 2 3/4 miles have been repaved. How many miles have not been repaved

Respuesta :

4 9/20 miles haven’t been paved. You have to set the denominators of the fractions equal to each other, which would be 20. Then, subtract the numbers to get your final answer.

Answer:

4 11/20

Step-by-step explanation:

The length of road unpaved is 7 3/10 less 2 3/4 miles  The LCD of the fractions is 20 (both 10 and 4 divide evenly into 20).

Thus, the problem becomes 7 6/20 - 2 15/20.

We have to borrow 1 from that 7 because 15/20 is larger than 6/20.  This results in

6 26/20 - 2 15/20, or

4 11/20
