Question

Find the unknown value in the proportion x∕32 = 38∕64.

Question 4 options:

A)

19

B)

38

C)

54

D)

76

Answer 1

x=19

Explanation:

This can be found in two ways.

Way #1

Since 32 is half of 64, divide 38 in half to get the missing number, or 19.

Way #2

Solve for x.

x/32 = 38/64

(Solve the expression on the right side)

x/32 = 0.59

(Multiply both sides by 32 to isolate the variable.)

x= 18.88 --> 19.

Answer 2

The answer is A. 19 since 32 is half of 64 so half of 38 is 19
