16 m 2 sm * 160 dm 2 sm 22 km 60 m * 22 060 m

2. Amallarni bajaring. (haqiqiy sonlar ustida amallar kompetensiyasini shakllantirish)

(865 420 -510 370) : 150 +410 ∙ 24

3. Tenglamani yeching.

x ∙ 4 +3 217 = 25 709 800 000 – 7 ∙ x = 857 643

4. Ifoda tuzing va uning qiymatini toping.

5. 73 va 80 ko’paytmasini 8 marta kamaytiring va hosil bo’lgan sondan 648 ni ayiring.
