Exercises: Interpreting Multiplication Equations as Multiplicative Comparisons
Work through each section in order. When a problem asks for an equation, write it exactly
in the form requested.
Recall / Warm-Up
Compute 4 x 3.
Compute 7 x 8.
Sara has 14 pencils. Mia has 6 pencils. How many more pencils does Sara have than Mia?
Fluency Practice
Maria has 4 times as many stickers as Tom. What does this comparison mean?
Tom's amount can be copied 4 times to make Maria's total -- Maria's amount is
4 equal groups of Tom's amount.
Maria has 4 more stickers than Tom.
Tom has 4 times as many stickers as Maria.
Maria's total is Tom's amount, plus 4 more groups the same size as Tom's amount,
added on top of Tom's own group (5 groups in all).
Which comparison statement correctly interprets the equation 42 = 6 x 7?
42 is 6 times as many as 7.
42 is 8 times as many as 7.
6 is 42 times as many as 7.
42 is 35 more than 7.
Given the equation 18 = 3 x 6, complete both comparison statements:
"18 is ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ times as many as 6" and "18 is ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ times as many as 3."
"40 is 8 times as many as 5." Complete the equation in the form
[large quantity] = [comparison factor] x [reference quantity]: ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ = ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ x ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ .
A pencil case holds 14 pencils. A pencil box holds 1 times as many pencils as the
pencil case. How many pencils does the pencil box hold?
A python is 9 times as long as a garter snake. The garter snake is 4 feet long. Which
equation represents the python's length p?
p = 9 x 4
p = 4 + 9
p = 9 x 9
4 = 9 x p
