Unit 4, Lesson 4

More than That, Less than That

Grade 7

Practice

Problem 1

Match each situation with a diagram.

Diego drank \(x\) ounces of juice. Lin drank \(\frac14\) less than that.
Lin ran \(x\) miles. Diego ran \(\frac34\) more than that.
Diego bought \(x\) pounds of almonds. Lin bought \(\frac14\) of that.

Problem 2

Elena walked 12 miles. Then she walked \(\frac{1}{4}\) that distance. How far did she walk all together? Select all that apply.

\(12 + \frac14\)
\(12 \boldcdot \frac14\)
\(12+\frac14 \boldcdot 12\)
\(12\left(1+\frac14 \right)\)
\(12 \boldcdot \frac34\)
\(12 \boldcdot \frac54\)

Problem 3

Write a story that can be represented by the equation \(y=x+\frac14x\).
