Question

In the scale model, the length of the table is centimeters. What is the length of the real table? (b)The height of the real table is inches. What is the height of the table in the scale model?

Answer 1

SOLUTION

Given the question in the image, the following are the solutions to the questions.

Question a: 4 centimeters to x inches

$\begin{gathered} 1\operatorname{cm}=6\text{ in} \\ 4\operatorname{cm}=x\text{ in} \\ By\text{ cross multiplication,} \\ x\times1=6\times4 \\ x=24\text{ inches} \end{gathered}$

Hence, the length of the real table is 24 inches.

Question b: the scale model of the real table with length of 12 inches

$\begin{gathered} 1\operatorname{cm}=6\text{ in} \\ ycm=12\text{ in} \\ By\text{ cross multiplication, we have} \\ 1\times12=6\times y \\ 12=6y \\ y=\frac{12}{6} \\ y=2\operatorname{cm} \end{gathered}$

Hence, the height of the table in the scale model is 2centimeters.
