The difference between and to the nearest tenth.
First convert the fraction to a decimal.
Subtract vertically, with the decimal points under each other. Put
a zero to the right of the last decimal digit so each number has
the same number of digits after the decimal point. Subtract from
the right to the left.
To approximate to the nearest tenth, look at the digit in the
hundredths place. 0 is less than 5, so leave out the digit at the
hundredths place and any other digits to the right.
