In a school, if the bell is rung at 45 minute intervals, how many times will the bell be rung in 3 hours?​

Answer 1

Explanation:

45 minutes is 3/4 of an hour.

how often does 3/4 fit into 3 ?

3 / 3/4 = 3/1 / 3/4 = (3×4)/(1×3) = 4

so, it will be rung 4 times.

Answer 2

Answer: 4 times.

Explanation:

We can divide 3 hours by 45 minutes, to get the number of times the bell will ring in 3 hours:

3 hours ÷ 45 minutes = 4

Therefore, the bell will be rung 4 times in 3 hours.

Think of it like this:

We can also think of it like this: 3 hours is 180 minutes, and the bell rings every 45 minutes.

So, we can divide 180 by 45 to get the number of times the bell will ring:

180 minutes ÷ 45 minutes = 4

Therefore, the bell will be rung 4 times in 3 hours.
