I variant

Ifodaning qiymatini toping: а) 0,255 ∙ 28; b) 8,354 ∙ 100.
Bo‘lishni bajaring: а) 93,15 : 23; b) 14, 706 : 100.
Ifodaning qiymatini toping: 3 ∙ 0,13 ∙ 0,5 ∙ 2.
Agar to‘g‘ri to‘rtburchakning tomonlari 3,5 sm va 4 sm bo‘lsa, uning yuzini hisoblang.
Tenglamani yeching: 8у + 5,7 = 24,1.

II variant

Ifodaning qiymatini toping: а) 0,436 ∙ 15; b) 7,263 ∙ 100.
Bo‘lishni bajaring: а) 13,59 : 18; б) 63,706 : 100.
Ifodaning qiymatini toping: 1,2 ∙ 7,09 ∙ 5 ∙ 10.
Agar to‘g‘ri to‘rtburchakning tomonlari 1,8 dm va 5 dm bo‘lsa, uning yuzini hisoblang.

5. Tenglamani yeching: 9х + 3,9 = 31,8.
