How do you multiply fractions?

Back

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

What is a mixed number?

Back

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

Front

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

Back

Multiply the whole number by the denominator and add the numerator. Place this result over the original denominator. For example, 2 1/2 = (2*2 + 1)/2 = 5/2.

Front

How do you add fractions with different denominators?

Back

Find the least common denominator (LCD), convert the fractions to equivalent fractions with the LCD, and then add the numerators.

What is the result of 1/2 + 1/4?

Back

1/2 + 1/4 = 2/4 + 1/4 = 3/4.

Front

How do you subtract fractions?

What is the result of 3/4 - 1/4?

Back

3/4 - 1/4 = 2/4 = 1/2.

Front

How do you divide fractions?

Back

To divide fractions, multiply by the reciprocal of the second fraction. For example, (a/b) ÷ (c/d) = (a/b) x (d/c).
