Answer 2

Answer:

here answer is 7/10

Step-by-step explanation:

both has 7/8 in common so

7/8(1/5+9/15)

=7/8(3/15+9/15)

=7/8(12/15) [in the complete question = is indicator mark.]

=7/2*1/5      (Now*stand for multiple and i think the question is already in distributive property as 7/8 is already distributed and 8 and are both multiples of 4.8=4*2,12=4*3 so we will get 7/2*3/15. now 3 and 15 are multiples of 3 where 3 is 1 times and 15 is 5 times so now we will get 7/2*1/5)

=7/10(as 7*1=7,2*5 is 10)

So,the answer is 7/10.
