Walking tours at a park begin every 25 minutes and bus tours begin every 45 minutes. Both tours start at 8:00 a.m. when the park opens. When is the next time the tours will start at the same time?

25 n = 45 m

5 * 5 n = 5 * 9 m
left * 9 , right * 5
9 * 25 = 225
9
5 * 45 = 225 sure enough
225 min = 3 .75 hr = 3 hr 45 min
how about 8 am + 3 hr 45 min = 11:45 am
