Write numbers first
35(\(\frac{4}{5}\)x)
Correct Answer
$27b$
Explanation
- Use the associative property of multiplication to regroup the factors
- 35(\(\frac{4}{5}x\)) = (\(\frac{35}{1}\) • \(\frac{4}{5}\))x
- Factor 35 as 5 • 7 and then remove the common factor 5
- = (\(\require{cancel} \frac{\cancel{5}^1 \cdot 7 \cdot 4}{1 \cdot \cancel{5}_1}\))x
- Do the multiplication and then simplify: \(\frac{28}{1}\) = 28
- = 28x
