# Ratio review

Learn how to find the ratio between two things given a diagram.
A ratio compares two different quantities.
For example, those two quantities could be monkeys and bananas:
Notice that there are start color blueD, 4, end color blueD monkeys and start color goldD, 5, end color goldD bananas.
Here are a few different ways we can describe the ratio of monkeys to bananas:
1. There are start color blueD, 4, end color blueD monkeys for every start color goldD, 5, end color goldD bananas.
2. The ratio of monkeys to bananas is start color blueD, 4, end color blueD to start color goldD, 5, end color goldD.
3. The ratio of monkeys to bananas is start color blueD, 4, end color blueD, colon, start color goldD, 5, end color goldD.
Order matters in ratios. Here are a few different ways to describe the ratio of bananas to monkeys:
1. There are start color goldD, 5, end color goldD bananas for every start color blueD, 4, end color blueD monkeys .
2. The ratio of bananas to monkeys is start color goldD, 5, end color goldD to start color blueD, 4, end color blueD.
3. The ratio of bananas to monkeys is start color goldD, 5, end color goldD, colon, start color blueD, 4, end color blueD.

## Let's practice!

Problem 1
Dana loves rocks! She has 6 pieces of granite, 3 pieces of marble, 14 pieces of sandstone, and 1 piece of slate.
What is the ratio of pieces of sandstone to pieces of marble in Dana's collection?
