Question

Express the ratio $45:60$ in its simplest form.

• A. $\frac{4}{3}$
• B. $\frac{3}{4}$
• C. $\frac{2}{3}$
• D. $\frac{5}{3}$

Answer 1

The correct option is B ($\frac{3}{4}$)

Given the ratio as $45:60$

HCF of $45=15\times 3$ and $60=15\times 4$ is $15$
$\therefore$ $\frac{45}{60}$ = $\frac{45÷15}{60÷15}=\frac{3}{4}$

Thus, the ratio $45:60$ in its simplest form is $3:4$.
