Fractions and Mixed Numbers: adding/sub/multi.

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 (part) and 'b' is the denominator (whole).

Front

What is a mixed number?

Back

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

Front

How do you add fractions with the same denominator?

Back

Add the numerators and keep the same denominator. For example, 1/4 + 2/4 = (1+2)/4 = 3/4.

Front

How do you subtract fractions with the same denominator?

Back

Subtract the numerators and keep the same denominator. For example, 3/5 - 1/5 = (3-1)/5 = 2/5.

Front

What do you need to do before adding or subtracting fractions with different denominators?

Back

You need to find a common denominator.

Front

What is the product of two fractions?

Back

To multiply two fractions, multiply the numerators together and the denominators together. For example, 1/2 x 3/4 = (1*3)/(2*4) = 3/8.

Front

True or False: You need common denominators when multiplying fractions.

Back

False.

Front

What is the first step in adding fractions with different denominators?

Back

Find the least common denominator (LCD) of the fractions.

Front

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

Back

Multiply the whole number by the denominator and add the numerator. For example, 2 1/3 = (2*3 + 1)/3 = 7/3.

Front

What is the process to reduce a fraction?

Back

Divide the numerator and the denominator by their greatest common factor (GCF). For example, to reduce 8/12, divide both by 4 to get 2/3.
