Question

$18\frac{1}{5} -(-22\frac{2}{5} )-(-40\frac{1}{5} )?$

Answer 1

Answer:

$=80\frac{4}{5}$

Step-by-step explanation:

$18\frac{1}{5}-\left(-22\frac{2}{5}\right)-\left(-40\frac{1}{5}\right)$

$=\frac{91}{5}-\left(-22\frac{2}{5}\right)-\left(-40\frac{1}{5}\right)$

$=\frac{91}{5}-\left(-\frac{112}{5}\right)-\left(-40\frac{1}{5}\right)$

$=\frac{91}{5}-\left(-\frac{112}{5}\right)-\left(-\frac{201}{5}\right)$

$=\frac{91}{5}+\frac{112}{5}+\frac{201}{5}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}$

$=\frac{91+112+201}{5}$

$\mathrm{Add\:the\:numbers:}\:91+112+201=404$

$=\frac{404}{5}$

$=80\frac{4}{5}$
