Question

1. a frame is 20 cm wide and 10 cm tall. if it is reduced to a width of 2 cm, then how tall will it be? 4) ted enlarged the size of a frame to a width

Explanation:

Step1: Set up proportion

Since the ratio of width to height remains the same, we have $\frac{20}{10}=\frac{2}{h}$, where $h$ is the new height.

Step2: Cross - multiply

$20h = 2\times10$.

Step3: Solve for $h$

$h=\frac{2\times10}{20}=1$.

Answer:

1 cm
