Common Core For Grade 6

• Students find the percent of a quantity. Given a part and the percent, students solve problems involving finding the whole.

Percent problems include the part, whole and percent. When one of these values is missing, we can use tables, diagrams, and models to solve for the missing number.

Example 1

Solve the following three problems.

Write the words PERCENT, WHOLE, PART under each problem to show which piece you were solving for.

60% of 300 = ____

60% of ____ = 300

60 out of 300 = ___%

How did your solving method differ with each problem?

Exercise 1

situation.
