Question

What is 16% of 43 minutes? Round answer to tenths place.​

Answer 1

16% of 43 minutes rounded off to tenths place is 6.9 minutes

Solution:

Given 16% of 43 minutes

To find: 16% of 43 minutes

In mathematics, a percentage is a number or ratio that represents a fraction of 100.

a % of b can be written as
`(a)/(100) * b`

so 16% of 43 minutes is expressed as:

`16 \% \text { of } 43 \text { minutes }=(16)/(100) * 43`

`16 \% \text { of } 43 \text { minutes }=0.16 * 43=6.88`

Thus 16 % of 43 minutes is 6.88 minutes

Rounding off rules:

First look at the digit to immediate right of rounding off digit

If that digit is less than 5, do not change the rounding digit but drop all digits to the right of it.

If that digit is greater than or equal to five, add one to the rounding digit and drop all digits to the right of it.

Rounding to tenths place:

In 6.88, the digit in tenths place is 8

8 is greater than five, so add one to the rounding digit and drop all digits to the right of it.

6.88 is rounded off to tenth place we get 6.9

Thus 16% of 43 minutes rounded off to tenths place is 6.9 minutes
