Answer: 7/4 or 1(3/4)-->Mixed fraction

Step-by-step explanation:

(3/4+4/5)+1/5

=[{(3*5)+(4*4)}/20]+1/5        //20 is coming from doing the LCM of 4 and 5 within the brackets. And then for equalizing the numerators, the numerators are multiplied with the same number the denominator is multiplied.

={(15+16)/20}+1/5

=31/20+1+5

={(31*1)+(1*4)}/20

=(31+4)/20

=35/20
