Answer 1

Answer:

(3a+2)/a(a+2)

Explanation:

(1/a)+(2/(a+2)

we cannot add any unlike fractions simply,we have to make it's denominator equal to add

you can do it by simply multiplication or by taking lcm of the the denominator!

here , it's 'a' and 'a+2'

now we got a modified denominator a(a+2), to make it fair to each term we have to multiply the extra multiplicand to numerator too

in case of 1/a, denominator becomes a(a+2) ,so we have to modify numerator also by multiplying the extra (a+2) to numerator also ,now 1/a becomes (a+2)/a(a+2)

---- similarly other term={2/(a+2)}can be modified as 2a/a(a+2)

now both denominator are equal , now new can add it simply by it's numerator

i.e, (a+2)/a(a+2) + 2a/a(a+2)

= (3a+2)/a(a+2)

it's from basic of fraction's addition!
