Question 1 • Grade 7 Mathematics

Julia is evaluating the expression 17 times 144 If she uses the distributive property to rewrite the expression with friendlier numbers, which expression can be a step in her work?

Answer
A
17 times 2 plus 17 times 72
B
17 times 100 times 17 times 40 times 17 times 4
C
17 times 2 times 17 times 72
D
17 times 100 plus 17 times 40 plus 17 times 4

Explanation

Using the distributive property, split 144 into friendlier addends: 144 = 100 + 40 + 4. Then 17 × 144 = 17 × (100 + 40 + 4) = 17 × 100 + 17 × 40 + 17 × 4. So the expression 17 times 100 plus 17 times 40 plus 17 times 4 is a valid step.
