And how the answer became 1/30
I'm confused
I will make brainliest for well answer

Answer 1

Step-by-step explanation:

-1/15+1/10

here we will take LCM of 15 and 10, since denominators are not same

5 | 15,10

| 3,2

LCM=5×3×2=30

-1/15×30 = -2

1/10×30 = 3

(-2+3)/30

(3-2)/30

1/v = 1/30

therefore v = 30 (take reciprocal on both side)
