Question

PLEASE HELP ASAP

Two clocks are turned on at the same time. One clock chimes every 15 minutes. The
other clock chimes every 25 minutes. In how many minutes will they chime together?

Answer 1

In 75 minutes, both clocks will chime together.

Explanation:

All you have to do is find the least common multiple of 15 and 25.

Multiples of 15:

15 x 1 = 15

15 x 2 = 30

15 x 3 = 45

15 x 4 = 60

15 x 5 = 75

Multiples of 25:

25 x 1 = 25

25 x 2 = 50

25 x 3 = 75

25 x 4 = 100

25 x 5 = 125

If you compare the two, you’ll find that 15 and 25 have a least common multiple of 75. So, in 75 minutes both clocks will chime at the same time
