Subtract : (-8/9) from (-3/5)

Answer»

(-8/9) from (-3/5)

We have:

= (-3/5) – (-8/9)

= (-3/5) + (additive inverse of -8/9)

= (-3/5) + (8/9)

LCM of 5 and 9 is 45

Express each of the given rational numbers with the above LCM as the common denominator.

Now,

= [(-3×9)/ (5×9)] = (-27/45)

= [(8×5)/ (9×5)] = (40/45)

Then,

= (-27/45) + (40/45)

= (-27+40)/45

= (13/45)
