Question

Decide whether the following proportion is true or false. (7)/(42)=(8)/(48)

Answer 1

Answer: True

Work Shown:

7/42 = 8/48

7/(6*7) = 8/(6*8)

1/6 = 1/6

This confirms that the original equation is true.

Another approach is to use the cross multiplication technique.

7/42 = 8/48

7*48 = 42*8

336 = 336
