Question

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

Answer 1

Answer:
`6.9\ minutes`

Explanation:

Let "x" represents the 16% of 43 minutes.

Once you analize the information given in the exercise, you can identify that 43 minutes is the 100%.

Then, with this data, you can set up the following proportion:

`(100)/(43)=(16)/(x)`

Now you must solve for "x". The steps are:

- Multiply both sides of the equation by "x"

`(x)((100)/(43))=((16)/(x))(x)\\\\(100x)/(43)=16`

- Multiply both sides by 43:

`(43)((100x)/(43))=(16)(43)\\\\100x=688`

- Divide both sides by 100:

`(100x)/(100)=(688)/(100)\\\\x=6.88`

- Rounding to the tenths place:

`x\approx6.9`
