To calculate equivalent fractions, take a fraction and divide or multiply both of its numbers by the same figure. An action must always be performed to both parts of the fraction when calculating equivalent figures.


To add mixed fractions, the fractions need to be converted to improper fractions with the same denominators. Once added, the sum needs to be converted back to a mixed fraction.


To divide mixed fractions, begin by changing each number to an improper fraction. This makes it easier to multiply the reciprocal of the divisor and to simplify when possible, then put the answer in its lowest terms. It is important to remember to multiply, instead of d...


A mixed number contains a whole number and a fraction. To estimate fractions with mixed numbers, add the benchmark of the fraction to the whole number.
