What is 2 over 8 plus 3 over 5?

2/8 + 3/5

Addition of fractions.

Steps to take.

#1 reduce any fraction ( 2/8 = 1/4) (NB Always reduce numbers to their smallest values; much easier to handle).

#2 bring to a common denominator of 20 ( 4 x 5)

#3 bring the numerators to equivalent values , by 'cross multiplying' 4 & 5'

Hence 1 x 5 = 5 & 3 x 4 = 12

#4 add the numerators 5 + 12 = 17

#5 place over the common denominator 17/20

(#6 check to see if fraction will reduce ; in this case ; NO; since '17' is a Prime number).

Laid out

2/8 + 3/5 =

1/4 + 3/5 =

[(1 x 5) + (3 x 4)] / ( 4 x 5)

[ 5 + 12 ] / 20

17/20

Done!!!!

So the answer is 17/20
