# Ratios, LCD and Simplification

1.)The ratio of strawberry ice cream lovers to vanilla is 9 to 5. If there are 144 more strawberry ice cream lovers than vanilla, how many of each are there?

2.) Find the LCD and convert each rational expression into an equivalent rational expression with the LCD as the denominator:

4/15xy^2, 3x/6y

3.) Simplify and write solution using only positive exponents: 7x^2yz^2/21x^3yx^7.

4.) Rewrite with a rational denominator: sqrt 5/sqrt 7
