Lesson 24 Application Problem

A long-time runner compiled her training distances in the chart below. Fill in the missing values.

Note: This Application Problem serves as a quick review of multi-digit multiplication and division with double-
digit divisors. Students must determine which operation is needed, and the review of whole number division can serve as an anticipatory set for today’s continuation into decimal divisors.
