5. Example 1 Maelynn needs to measure cup of milk, but only has a
cup measuring cup. How many times will she need to fill
it?
Write the problem
Draw picture that represents
the dividend.
Circle sets of divisors.
Count how many sets of the divisor fit in the dividend. There are 3 circled sets.
Maelynn will need to fill the cup 3 times.

6. Example 2 Clint need to make a platform that is inch thick. He has
boards that are each of an inch thick. How many
boards does he need to make the platform?
Write the problem.
Rename with common denominators.
