A. 42
B. 6
C. 13
D. 1

Answer 1

If you would like to solve the equation 7/8 = x/48, you can calculate this using the following steps:

7/8 = x/48 /*48
x = 7/8 * 48
x = 42

The correct result would be A. 42.

Answer 2

7/8 = x/48

Perform cross multiplication:
a/b = c/d
ad = bc

a = 7 ; b = 8 ; c = x ; d = 48
7*48 = 8x
336 = 8x
336/8 = x
42 = x

7/8 = 42/48

42 ÷ 6 = 7
48 ÷ 6 = 8
