Question

A factory makes boxes with length to width ratios of 3 cm to 1 cm . what should be the length of a box with a width of 33 cm ?

Answer 1

Since we know the length (L) to width (W) ratio is 3 to 1, we can put the ratio in the form of a fraction and solve for the unknown length (L’).

Therefore we have L/W = 3/1 = L’/33

Moving the width of 33 to the other side of the equation, we have 3/1 * 33 = L’

99/1 = L’

99 = L’

Therefore the length L’ should be 99cm if the width is 33cm.
