Explanation:

Step1: Find GCD of 16 and 40

The greatest common divisor (GCD) of 16 and 40. Factors of 16: 1, 2, 4, 8, 16. Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40. GCD is 8.

Step2: Divide numerator and denominator by GCD

Divide 16 and 40 by 8. $\frac{16\div8}{40\div8}=\frac{2}{5}$

Answer:

$\frac{2}{5}$
