#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
