Answer 1

8/5 + 3/9= 24/15+5/15=29/15

15/12- 10/5= 75-120/60=-3/4

12/6 + 9/8=25/8

20/16 - 14/12=1/12

2/3 x 2/4=4/12= 1/3

Answer 2

Respuesta:
8/5+3/9= 87/45= 29/15 (esto es simplificado)
15/12-10/5= 45/20= 9/4

12/6+9/8= 150/48= 75/24= 25/8

20/16-14/12= 16/192= 8/96= 4/48= 2/24= 1/12

2/3×2/4= 4/12= 2/6= 1/3
