Answer:

=80(4)/(5)

Explanation:

$18(1)/(5)-\left(-22(2)/(5)\right)-\left(-40(1)/(5)\right)$

$=(91)/(5)-\left(-22(2)/(5)\right)-\left(-40(1)/(5)\right)$

$=(91)/(5)-\left(-(112)/(5)\right)-\left(-40(1)/(5)\right)$

$=(91)/(5)-\left(-(112)/(5)\right)-\left(-(201)/(5)\right)$

=(91)/(5)+(112)/(5)+(201)/(5)

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

=(91+112+201)/(5)

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

=(404)/(5)

=80(4)/(5)
