Question

solve the sum step by step with explaining LCM... ​

Answer 1

Answer:

v=-30. l

Explanation:

LCM is 30 then1/v=1/-30

Answer 2

we can write it as

$\frac{ 1}{v} = \frac{1}{ 15} - \frac{1}{10}$

10=2×5

15=3×5

5 is common so we take 5 only once

so

L.C.M=2×3×5=30

$\frac{1}{v} = \frac{2 - 3}{30 }$

$\frac{1}{v } = \frac{ - 1}{30}$

by cross multiplication

v= -30
