Front

What is a common denominator?

Back

A common denominator is a number that is a multiple of the denominators of two or more fractions, allowing them to be added or subtracted.

What is the process to find a common denominator for 3/10 and 1/5?

Back

The common denominator for 3/10 and 1/5 is 10, as it is the least common multiple of 10 and 5.

Front

How do you multiply fractions?

Back

To multiply fractions, multiply the numerators together and the denominators together. For example, (a/b) * (c/d) = (a*c)/(b*d).

What is the result of 1/5 + 4/15?

Back

The result is 7/15 after finding a common denominator and adding the fractions.

Front

How do you divide fractions?

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction, such as 2 1/4.

Front

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