Fractions trip people up because adding them needs a common denominator while multiplying does not, and the answer should be simplified at the end. Enter two fractions and an operation to get the result reduced to lowest terms, with the steps that got there.

Good to know
Add needs a common denominator; multiply does notTo add or subtract, the bottoms must match first. To multiply, you just multiply across. Mixing up the two rules is the classic slip.
Always simplify at the end6/8 and 3/4 are the same value, but 3/4 is the expected answer. Reducing makes results easier to read and compare.
Mixed numbers and improper fractionsSeven-thirds and two-and-a-third are equal. Convert to an improper fraction before calculating, then back if you want a mixed number.
Decimals are sometimes clearerFor money or measurements a decimal often reads better than a fraction. Use whichever fits the task.
