Find:

(a) \[43.15\div 5=?\]

(b) \[82.44\div 6=?\]

Answer:

(a) \[43.15\div 5=\frac{4315}{100}\div 5=\frac{4315}{100}\times \frac{1}{5}\]

\[=\frac{4315\times 1}{100\times 5}=\frac{1}{100}\times \frac{4315}{3}\]

\[=\frac{1}{100}\times 863=\frac{863}{100}=8.63\]

(b) \[82.44\div 6=\frac{8244}{100}\div 6=\frac{8244}{100}\times \frac{1}{6}\]

\[=\frac{8244\times 1}{100\times 6}=\frac{1}{100}\times \frac{8266}{6}\]

\[=\frac{1}{100}\times 1374\]

\[=\frac{1374}{100}=31.74\]
