Question

Solve the proportion five point two over eight = y over six A. y = 4.22 B. y = 6.93 C. y = 2.86 D. y = 3.90

Answer 1

D.y = 3.9

Explanation:

we can express the word problem five point two over eight = y over six mathematically;

`(5.2)/(8) = (y)/(6)`

our unknown is y, so we will keep rearranging the equation by using simple principles of algebra until we get y

cross multiply;

y×8 =5.2×6

y×8 =31.2

divide through by 8

y×8÷8 =31.2÷8

y=3.9

The correct answer is D
