Question

What should be added to the sum 13/15 and 27/20 to get 91/60

​

Answer 1

Answer:

The answer is -7/10.

Step-by-step explanation:

let the required no. be x.

13/15+27/20+x=91/60

(52+81+60x)/60=91/60

(133+60×)=91. {60 vanishes by cross multiplication}

60x=91-133

60x= -42

x = -42/60

x = -7/10
