Question

A bag of mayonnaise has 14 grams. It has 11 grams of fat- what percent of fat does it have to the nearest tenth?

Answer 1

`0.8 %` to 1 decimal place

Explanation:

Nearest tenth is the first decimal place.

as a fraction the fat content is `11/14`

Let the unknown value be `x` then we have

`11/14=x/100`

Multiply both sides by 100

`x=11/14xx100 = 0.785714.....`

The column for tenths is the one with 7 in it. The next column to the right has 8 in it. As 8 satisfies the criterion of 5 or greater we round the 7 up by 1 giving:

`0.8 %` to 1 decimal place
