Aaron needs 24 inches of copper wire for an experiment. The wire is sold by the centimeter. Given that 1 inch = 2.54 centimeters

tatiyna

$\frac{1}{2.54} =\frac{24}{x}$

Multiply both sides by 2.54.

$1=\frac{24}{x} (2.54)$

$= \frac{60.96}{x}$

Multiply both sides by x.

x = 60.96

Hence, Aaron needs 60.96 centimeters of wire.
