**Example 1:** Find the proper fraction addition of 3/5 + 1/5.

**Solution:** Both fractions have like denominators. i.e 5

Add both fractions i.e 3/5 + 1/5 = 4/5

Proper fraction addition of

** 3/5 + 1/5 ** = 4/5.

**Example 2:** Find the proper fraction addition of 10/12 + 3/9.

**Solution:** Both fractions have unlike denominators, make the denominator same by finding LCM of denominators. i.e 30/36 and 12/36

Add both fractions i.e 30/36 + 12/36 = 7/6

Proper fraction addition of

** 10/12 + 3/9 ** = 7/6.

**Example 3:** Find the proper fraction addition of 2/11 + 4/6.

**Solution:** Both fractions have unlike denominators, make the denominator same by finding LCM of denominators. i.e 12/66 and 44/66

Add both fractions i.e 12/66 + 44/66 = 28/33

Proper fraction addition of

** 2/11 + 4/6 ** = 28/33.

**Example 4:** Find the proper fraction addition of 8/16 + 4/32.

**Solution:** Both fractions have unlike denominators, make the denominator same by finding LCM of denominators. i.e 16/32 and 4/32

Add both fractions i.e 16/32 + 4/32 = 5/8

Proper fraction addition of

** 8/16 + 4/32 ** = 5/8.

**Example 5:** Find the proper fraction addition of 7/10 + 8/12.

**Solution:** Both fractions have unlike denominators, make the denominator same by finding LCM of denominators. i.e 42/60 and 40/60

Add both fractions i.e 42/60 + 40/60 = 41/30

Proper fraction addition of

** 7/10 + 8/12 ** = 41/30.
