A mathematics textbook has 6 pages of instruction for every 2 pages of practice problems. How many pages of instruction does it have for every page of practice problem?

Answer 1

You would like to figure out how many pages of instruction are needed for one page of practice problems. One page of problems is HALF as much of the two pages you were given - that means you also will need HALF as many pages of instruction. Half of 6 is 3!

Answer 2

Unit rate is found simply by dividing.

6 pages of instruction/2 pages of practice problems = 3 pages of instruction per page of practice problems
