Question

A photographer uses a computer program to enlarge a photograph. What is the scale according to which the width has enlarged?

✓

Answer

By the given graph, we have width before editing $= 2$ units Width after editing $= 4$ units
We know that, $\text {Scale}=\frac{\text{Size berfore editing}}{\text{Size after editing}}$
$\therefore \text{Scale}=\frac{2}{4}=\frac{1}{2}=1:2$
Hence, scale used to enlarge the photograph is $1:2$
