3-misol

. (80 + 60) : 2=140:2=70 (90 + 120) : 3=210:3=70

(240 + 320) : 80 =560:8= 70 (100+50) : 50= 150:50=3

(80 + 160) : 40 = 240:40=6 (180 + 540) : 9=720:9=80

4. Yechilishini tushuntiring:

86 : 2= (80+6):2= 80:2+6:2= 40+3=43 84 : 4=80:4+4:4=20+1=21

55 : 5 88 : 8

66 : 6 96 : 3 63 : 3 48 : 2

Namuna: 86 : 2 = (80 + 6) : 2 = 80 : 2 + 6 : 2 = 40 + 3 = 43
