Step 1 Find the least common denominator of the two fractions. Step 2 Change each fraction to an equivalent fraction having the least common denominator. Step 3 Find the difference of the numerators and place this result over the least common denominator. Step 4 Simplify (or reduce) the fraction obtained in step 3.

Step 1: Separate the whole number from the fractions. Step 2: Now we will add the whole numbers together and add the fractions together. To add the fractions we need common denominators. Now that we have common denominators, we can add the numerators and leave the denominator the same.

Subtracting mixed fractions with unlike denominators? You could first find a common denominator and use it to rewrite each fraction. Then, subtract the whole numbers and fractions separately.

If the whole number is odd, divide it in half and round the decimal down to the nearest whole number. Add the numerator and denominator of the fraction together to get the new numerator. Multiply the old denominator by 2 to get the new denominator. For example, to halve 3 1/2, divide 3 / 2 = 1.5 (round down to 1).
