Answer 2

Step-by-step explanation:

Solutions:-

a)

Given expression is a/2 + 1/5

LCM of 2 and 5 = 10

=> [(a×5)+(1×2)]/10

=> (5a+2)/10

a/2 + 1/5 = (5a+2)/10

b)

Given expression is 1/2 + x/5

LCM of 2 and 5 = 10

=> [(1×5)+(x×2)]/10

=> (5+2x)/10

1/2 + x/5 = (5+2x)/10

c)

Given expression is n/5 + 2/3

LCM of 5 and 3 = 15

=>[(3×n)+(2×5)]/15

=> (3n+10)/15

n/5 + 2/3 = (3n+10)/15

d)

Given expression is n/3 - 2/5

LCM of 3 and 5 = 15

=> [(n×5)-(2×3)]/15

=> (5n-6)/15

n/3 - 2/5 = (5n-6)/15
