Flashcard 9 - Subtest II: Mathematics Flashcard Set for the CSET Multiple Subjects Test

Back

The correct answer is:

\[28x^{3}\]

Explanation:

We need to change the denominator \(16y\) to \(64x^{2}y\)

Multiplying by \(\frac{4x^{2}}{4x^{2}}\) will do that.

\[\frac {4x^{2}}{4x^{2} }\cdot \frac{7x}{16y}= \frac{28x^{3}}{64x^{2}y}\]
