Exercise 17 Page 208

Use the Multiplication Property of Equality to eliminate the division.

v=10.5, see solution.

Practice makes perfect
Notice that in the given equation v is only present within the numerator of a single fraction. 3/4 = v/14 Let's use the Multiplication Property of Equality and multiply multiply both sides of the equation by 14. This will eliminate the denominator of the fraction and isolate v.
3/4 = v/14
14 * 3/4 = 14 * v/14
14 * 3/4 = v
42/4 = v
10.5 = v
v=10.5
