Answer 1

Answer:

A. 4 11/20

Step-by-step explanation:

So you have to subtract the total (7 3/10) by what already has been repaved (2 3/4). If you convert it into decimals, that would give you 7.3-2.75. Subtracting would give you 4.55. Your final answer has to be a fraction though so you have to convert back into a fraction. 0.55 is 55/100 which can be simplified to $\frac{5(11)}{5(20)}$. Canceling out the 5 will result in 11/20.

Your final answer would be 4 11/20 (A)
