Question

Как сделать помогите пожалуйста

Answer 1

(1) 3/4 = (3×25)/(4×25) = 75/100 ;
1/2 = (1×50)/(2×50) = 50/100 ;
3/5 = (3×20)/(5×20) = 60/100 ;
3/10 = (3×10)/(10×10) = 30/100 ;
9/20 = (9×5)/(20×5) = 45/100 ;
2/25 = (2×4)/(25×4) = 8/100 ;
9/50 = (9×2)/(50×2) = 18/100

(2) 2/3 = (2×20)/(3×20) = 40/60 ;
1/2 = (1×30)/(2×30) = 30/60 ;
3/4 = (3×15)/(4×15) = 45/60 ;
1/6 = (1×10)/(6×10) = 10/60 ;
4/15 =(4×4)/(15×4) = 16/60 ;
7/20 = (7×3)/(20×3) = 21/60 ;
11/30 = (11×2)/(30×2) = 22/60
