front wheels of a cart have a circumference of 3 metres.back wheels have a circumference of 4 metres.A white dot is painted on the rim of each wheel it touches the ground.the cart is then driven 100 metres.including the starting position,how many times will the white dots be on the ground together?

• math -

The least common multiple of 3 and 4 is 12.

100 / 12 = 8.3

Including the starting position, the white dots will be on the ground together 9 times.
