0.8 %0.8% to 1 decimal place

Explanation:

Nearest tenth is the first decimal place.

as a fraction the fat content is 11/141114

Let the unknown value be xx then we have

11/14=x/1001114=x100

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
