Below are sample questions representative of the exercises included on this worksheet and related 3.51 Unknowns in Multiplication and Division Equations skill assessments:

Problem 1Difficulty: Mastery

Find the value of the unknown. Equation: ? = 36 ÷ 9 What is ? and which operation would you use?

A? = 4; use division

B? = 72; use division

C? = 4; use multiplication

D? = 9; use multiplication

Solution & Explanation:In ? = 36 ÷ 9, you can use division to find the missing quotient or divisor. Compute the division so the equation is true; ? = 4.

Problem 2Difficulty: Mastery

Yumi compares two equal products. Equation: 3 × ? = 8 × 3 What is ? and which operation would you use to find it?

A? = 8; use division

B? = 8; use multiplication

C? = 4; use division

D? = 10; use multiplication

Solution & Explanation:In 3 × ? = 8 × 3, ? is a missing factor. Divide the known product by the known factor to find it: ? = (product) ÷ (factor) = 8.

Problem 3Difficulty: Mastery

Xavi solves an equation with a division expression. Equation: 3 × ? = 144 ÷ 12 What is ? and which operation would you use to find it?

A? = 4; use division

B? = 2; use multiplication

C? = 3; use division

D? = 4; use multiplication

Solution & Explanation:First simplify the side without ?. Then ? is a missing factor in 3 × ? = 144 ÷ 12, so use division to find it. The value is 4.
