Question

Find the sum:

`(-8)/19 + (-2)/57`

Sum

Solution

Given, `(-8)/19 + (-2)/57`

= `(- 8)/19 - 2/27`

Now the LCM of the denominator of the former parameter = 57

= `((- 8 xx 3) - (2 xx 1))/57`

= `(- 24 - 2)/57`

= `(- 26)/57`

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

Hence, `(- 26)/57`
