Solve Multi-Step Problems with Rational Numbers in Any Form

Convert a value between fraction, decimal, and percent form

Estimate the answer to a multi-step rational-number problem using rounding and mental math, then check it against the exact computation

Solve a multi-step real-world problem involving positive and negative rational numbers in any form

Work through the converting-formats chart as a warm-up before the estimation and practice problems, since later problems mix fraction, decimal, and percent values

Have students record an estimate before calculating the exact answer, then compare the two, following the estimation page's own structure

Use the multiple-choice test-practice set as a follow-up check after the open-ended practice problems. Practice checking whether answers are reasonable with this estimate and calculate worksheet.

Rational-number form conversion -- students convert values among fraction, decimal, and percent form using a guided chart.

Estimation and reasonableness checking -- students round and mentally compute an approximate answer, then verify it against an exact multi-step calculation.

Multi-step problem solving with rational numbers -- students combine operations on positive and negative fractions, decimals, and percents to solve real-world word problems.
