Question

What is the value of d in the equation?

1 3/4 d = 14


A. 4

B. 8

C. 18 2/3

D. 24 1/2​

Answer 1

B: 8

Explanation:

1 3/4 is equivalent to the improper fraction 7/4. Then:

(7/4)d = 14

Eliminate the fraction by multiplying both sides by 4:

7d = 4(14)

Divide both sides by 7 to isolate (solve for) d:

d = 4(2) = 8

B is the correct answer
