How do you convert a mixed number to an improper fraction?

Back

To convert a mixed number to an improper fraction, multiply the whole number by the denominator, add the numerator, and place that sum over the original denominator.

Front

What is the process to find the total amount of ingredients needed when given two different measurements?

Back

To find the total amount of ingredients, convert each measurement to a common denominator if they are fractions, then add the numerators together.

Front

How do you simplify a fraction?
