Answer 1

(3/4+5/3)+(7+1/5) = 577/60

(3/4+5/3)+(7+1/5) ; 3/4 = (3×15)/(4×15) = 45/60

= (45/60+5/3)+(7+1/5) ; 5/3 = (5×20)/(3×20) = 100/60

= (45/60+100/60)+(7+1/5) ; 7 = (7×60)/(1×60) = 420/60

= = (45/60+100/60)+(420/60+1/5) ; 1/5 = (1×12)/(5×12) = 12/60

= (45/60+100/60)+(420/60+12/60)

= (45+100+420+12)/60

= ((45+100)+420+12)/60

= (145+(420+12))/60

= (145+432)/60

= 577/60
