<h3>Proportion</h3>
Proportion says that two ratios (or fractions) are equal. This a mathematical comparison between numbers.
Therefore, let's establish the proportion in this situation
- Malik height / Malik shadow = Jeremy height / Jeremy shadow
Therefore,
cross multiply
72 × 56 = 60x
60x = 4032
divide both sides by 60
x = 4032 / 60
x = 67.2
Therefore, Jeremy's height is 67.2 inches
