Question

the scale of a real life object to the reduced scale drawing is 5:2. if a hammer is 10cm long, then how long is the reduced scale drawing of the hammer?

Explanation:

Step1: Set up proportion

Let the length of the reduced - scale drawing be $x$ cm. The proportion is $\frac{5}{2}=\frac{10}{x}$.

Step2: Cross - multiply

$5x = 2\times10$.

Step3: Solve for $x$

$5x=20$, so $x = \frac{20}{5}=4$.

Answer:

4
