1) Find the least common denominator .
2) Write both original fractions as equivalent fractions with the least common denominator. All Operations With Fractions Worksheet
3) Add (or subtract) the numerators.
4) Write the result with the denominator.
Example 1:
Add 1 3 + 3 7 .
The least common denominator is 21 .
1 3 + 3 7 = 1 ⋅ 7 3 ⋅ 7 + 3 ⋅ 3 7 ⋅ 3 = 7 21 + 9 21 = 16 21
To multiply two fractions:
1) Multiply the numerator by the numerator. Numbers And Operations Fractions
2) Multiply the denominator by the denominator. Operations With Fractions Review
For all real numbers a , b , c , d ( b ≠ 0 , d ≠ 0 )
a b ⋅ c d = a c b d
Example 2:
Multiply 1 4 ⋅ 5 6 .
1 4 ⋅ 5 6 = 1 ⋅ 5 4 ⋅ 6 = 5 24
To divide by a fraction, multiply by its reciprocal .
For all real numbers a , b , c , d ( b ≠ 0 , c ≠ , d ≠ 0 )
a b ÷ c d = a b ⋅ d c = a d b c Order Of Operations With Fractions

Divide 3 4 ÷ 5 7 .
3 4 ÷ 5 7 = 3 4 ⋅ 7 5 = 3 ⋅ 7 4 ⋅ 5 = 21 20
Mixed numbers can be written as an improper fraction and an improper fraction can be written as a mixed number.
Example 4:
Write 7 2 5 as an improper fraction.
7 2 5 = 7 1 + 2 5 = 7 ⋅ 5 1 ⋅ 5 + 2 5 = 35 5 + 2 5 = 37 5
Example 5:
Write 11 7 as a mixed number in simple form.
11 7 = 11 ÷ 7 = 1 R 4
Therefore, 11 7 = 1 4 7 .
A fraction is in lowest terms when the numerator and denominator have no common factor other than 1 . To write a fraction in lowest terms, divide the numerator and denominator by the greatest common factor .
Example 6:
Write 45 75 in lowest terms.
45 and 75 have a common factor of 15 .
45 75 = 45 ÷ 15 75 ÷ 15 = 3 5
