(-9/7) from (-1)
We have:
= (-1/1) – (-9/7)
= (-1/1) + (additive inverse of -9/7)
= (-1/1) + (9/7)
LCM of 1 and 7 is 7
Express each of the given rational numbers with the above LCM as the common denominator.
Now,
= [(-1×7)/ (1×7)] = (-7/7)
= [(9×1)/ (7×1)] = (9/7)
Then,
= (-7/7) + (9/7)
= (-7+9)/7
= (2/7)
