-misol. Jadvalni toldiring:
1) Boluvchi va bolinma malum bolsa, bolinuvchi qanday topiladi?
2) Bolinuvchi va bolinma malum bolsa, boluvchi qanday topiladi?
3) Tenglamalarni yechishni va tekshirishni tushuntiring:
x : 4 = 150 9 018 : x = 18
x = 1504 x = 9 018 : 18
x = 600 x = 501
Te k s h i r i s h : Te k s h i r i s h :
600 : 4 = 150 9 018 : 501 = 18
150 = 150 18 = 18
2-misol.
x : 35 = 16 800 357 000 : x = 357
x=16800*35 x=357 000:357
x=588 000 x=1000

588000:35=16800 357 000:1000=357
3-misol. Masalalarni tenglama tuzib yeching:
1) Nomalum son 8 marta orttirilsa, 1 392 hosil boladi. Nomalum sonni toping.
2) Oylangan son 8 ta kamaytirilsa, 3 485 hosil boladi. Qanday son oylangan?
1)x*8=1392 2)x-8=3485
X=1392:8 x=3485+8
X=174 x=3493
