Multiplying Fractions

Front

What is a fraction?

Back

A fraction represents a part of a whole and is written as 'a/b', where 'a' is the numerator (the number of parts) and 'b' is the denominator (the total number of equal parts).

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 fraction, such as 2 1/3.

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 1/3 = (2*3 + 1)/3 = 7/3.

What is the area of a rectangle?

Back

The area of a rectangle is found by multiplying its length by its width. For example, if a rectangle is 3 yards long and 2 yards wide, its area is 3 x 2 = 6 square yards.

Front

What is the area of a square?

Back

The area of a square is found by squaring the length of one of its sides. For example, if one side is 4 yards, the area is 4 x 4 = 16 square yards.

How do you find a fraction of a whole number?

Back

To find a fraction of a whole number, multiply the whole number by the numerator and then divide by the denominator. For example, to find 3/4 of 8, calculate (3*8)/4 = 6.

Front

What does it mean to simplify a fraction?

Back

Simplifying a fraction means reducing it to its lowest terms, where the numerator and denominator have no common factors other than 1.

Front

What is the least common denominator (LCD)?

Back

The least common denominator is the smallest number that can be a common denominator for two or more fractions.

Front

How do you add fractions with different denominators?

Back

To add fractions with different denominators, first find the least common denominator, convert each fraction to an equivalent fraction with the LCD, and then add the numerators.
