I'll show you the first two.

1. Find the LCD of 3/5 and 1/6.

a. 5
b. 6
c. 11
d. 30

The LCD is the smallest number divisible by both denominators.
Let's look at the multiples of 6:
6, 12, 18, 24, 30. The only one of those numbers that's also divisible by 5 is 30.


2 Add the fractions and write your answer in lowest terms.

2/5 + 1/9

a. 1/15
b. 23/45
c. 3/14
d. 19/45

The least common denominator must be 45.
2/5 = 18/45
1/9 = 5/45

Add the numerators to find your answer.

I'll be glad to check your work and answers for the other three problems.
