Step-by-step explanation:

$\small \: 4 + \frac{9}{100} + \frac{6}{10} \\$

$\small4 + \frac{9}{100} + \frac{3}{5} \\$

$\small \frac{100 \times 4}{100 \times 1} + \frac{9}{100} + \frac{ 3 \times 20}{5 \times 20} \\$

common denominator is 100

$\small \frac{400}{100 \times 1} + \frac{9}{100} + \frac{ 60}{100} \\$

Add the numerator

$\small \frac{400 + 9 + 60}{100 \times1} \\$

$\small \frac{469}{100 \times 1} \\$

Divide we get
