Question

Find the sum:

`(-9)/10 + 22/15`

Sum

Solution

`(-9)/10 + 22/15`

Now the LCM of the denominator of the latter parameter = 30

= `((- 9 xx 3) + (22 xx 2))/30`

= `(- 27 + 44)/30`

= `17/30`

The numerator and denominator of the obtained rational number have no other multiple than 1.

Hence, =`17/30`
