Question

Express ration into simplest form? 4 hours to 90 minutes

Answer 1

The simplified form of the ratio is `3` minutes to `8` minutes or `3/8`.

Explanation:

First, we need to get both numbers in the same form. The `90` is in minutes, but the `4` is in hours. There are `60` minutes in one hour, so we get the following.

`4*60=240`

Now, we have `240` minutes to `90` minutes. It can also be written like this.

`90/240`

To simplify this ratio, we need to find the greatest common denominator of the two numbers. In other words, we need to find the largest number that both of them are divisible by. In this case, that number is `30`. We simplify the equation by dividing both sides by this number.

`(90/30)/(240/30)=3/8`
