Question

subtract the sum of -5/8 and 7/10 from the sum of -3/5 and 8/15

Answer 1

Answer:

-17/120

Step-by-step explanation:

-5/8 + 7/10

LCM of 8 and 10 is 40

-25/40 + 28/40 = 3/40 ---(1)

-3/5 + 8/15

LCM of 5 and 15 is 15

-9/15 + 8/15 = -1/15 ---(2)

Subtracting (1) from (2),

-1/15 - 3/40

LCM of 15 and 40 is 120

-8/120 - 9/120 = -17/120
