Question

-4/5 + (-3/8) = what

Answer 1

Answer:

-1.175

Step-by-step explanation:

-4/5 + (-3/8) = -4/5 + (-3/8) = -4 · 8/5 · 8 + (-3) · 5/8 · 5 = -32/40 + (-15/40) = -32 + (-15)/40 = -47/40

The common denominator you can calculate as the least common multiple of the both denominators - LCM(5, 8) = 40. The fraction result cannot be further simplified by cancelling.

In words - minus four fifth plus minus three eighth = minus forty-seven fortieth.
