To do this, you have to cross multiply. (It helps if you write this down on paper as you read). So,

3 over 8 = n (unknown number) over 56.

Then you use a trick called cross multiplication. You just multiply the numbers diagonal from each other and your equation equals 3x56=8n. Get it?

When you multiply 3 and 56, you get 168=8n.

From here, you divide both sides by 8 to get what n equals. 168/8=8n/8.

When you divide 168 and 8, you get 21. So, n=21. 3 eighths of 56 equals 21! :)
