Nope.

They'd chime together at 1:30.

Can you explain how to do this problem. Thanks
Ms. Sue
The clock that chimes every half hour chimes at 1:00, 1:30, 2:00, etc.

The clock that chimes every 15 minutes chimes at 1:00, 1:15, 1:30, 1:45, 2:00, etc.

Ms. Sue
30 minutes is 1/2 hour
15 minutes is 1/4 hour
