Question

What is 40 percent of an hour? please write answer into hours and minutes. I will mark brainliest!!!!!

Solution 1

There are 24 **minutes **in 40 **percent **of an hour.

The percentage is defined as a **ratio **expressed as a **fraction **of 100.

For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

We know that there are 60 **minutes **in one **hour**

So 1 hour = 60 minutes,

We have to evaluate 40 **percent **of an hour

⇒ 40% of 1 hour

⇒ 40% of 60 minutes

⇒ 0.4 × 60 minutes

Apply the **multiplication **operation, and we get

⇒ 24 minutes

There are 24 **minutes **in 40 percent of an hour.
