Find the sum:
`(-9)/10 + 22/15`
Advertisements
उत्तर
`(-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`
