Practice
Problem 1
Solve each equation.
- \(4a=32\)
- \(4=32b\)
- \(10c=26\)
- \(26=100d\)
Problem 2
Solve each equation.
- \(2x = 5\)
- \(y + 1.8 = 14.7\)
- \(6 = \frac{1}{2} z\)
- \(3\frac{1}{4} = \frac{1}{2} + w\)
- \(2.5t = 10\)
Problem 3
For each equation, draw a tape diagram that represents the same relationship.
- \(3\boldcdot x = 54\)
- \(9+p=28\)
- \(17 - 6 = x\)
Problem 4
Find each product.
\((21.2)\boldcdot (0.02)\)
\((2.05)\boldcdot (0.004)\)
Problem 5
For a science experiment, students need to find 25% of 60 grams.
- Jada says, “I can find this by calculating \(\frac{1}{4}\) of 60.”
- Andre says, “25% of 60 means \(\frac{25}{100} \boldcdot 60\).”
Do you agree with either of them? Explain your reasoning.
