If a doctor gives you 3 pills and tells you to take one pill every half hour, how long would it take before all the pills had been taken?

Well, we'd add up a half hour.

0:30 - 1 pill

1:00 - 2 pills

1:30 - 3 pills

All the pills have been taken.

It took an hour and a half.

Therefore, your answer is 1 1/2 hours.

Glad I could help, and good luck!

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
