Question

Match the following:

• A. 5x
• B. 4z
• C. 4x
• D. xy

Answer 1

$\frac{25x^2}{5x}=\frac{5\times 5\times x\times x}{5\times x}=5x$

$\frac{12xy}{3xyz}=\frac{2\times 2\times 3\times x\times y}{3\times x\times y\times z}=\frac{4}{z}$

$\frac{24x^3}{6x^4}=\frac{2\times 2\times 2\times 3\times x\times x\times x}{2\times 3\times x\times x\times x\times x}=\frac{4}{x}$

$\frac{20xy}{20}=\frac{20\times xy}{20}=xy$
