Example 1: Change .0375 to a common fraction in its

Example 2: Change 8.125 to a mixed number in its lowest terms.

Note that the number after "of" is the denominator of the result

ing fraction.

Always reduce the resulting fraction to its lowest terms.

Find what fractional part:

Express as a common fraction and as a decimal fraction, the

Express as a common fraction and as a decimal fraction :

To add fractions, reduce them to fractions having the least common denominator and then add the numerators for the numerator of the sum. Reduce the sum to its lowest terms.

To subtract fractions, reduce them to fractions having the least common denominator and then subtract the numerators for the numerator of the difference. Reduce the difference to its lowest terms.

To prevent mistakes:

1. Write figures carefully.

2. Do not crowd your figures.

3. Do not add numerators and denominators. Separate them so that you can tell at once which are the numerators.

4. Check every calculation.

First find the sums, then find the differences :

Remember:

To add or subtract common and decimal fractions reduce them all to common fractions or to decimal fractions; then add or subtract
