3.05 ni kasrga aylantiring.
61/20
0.7 va 1.2 ni qo‘shing.
0.7 + 1.2 = 1.9
3.4 ni 0.2 ga ko‘paytiring
3.4 × 0.2 = 0.68
1.2 ni 2 ga bo‘ling.
1.2 ÷ 2 = 0.6
2.7 dan 1.4 ni ayiring.
2.7 - 1.4 = 1.3
0.05 ni 0.25 ga ko‘paytiring
0.05 × 0.25 = 0.0125
3.4 va 1.6 ni qo‘shing, natijadan 2.2 ni ayiring
(3.4 + 1.6) - 2.2 = 2.8
(0.4 × 1.5) + (0.3 × 2.5) ni hisoblang
(0.4 × 1.5) + (0.3 × 2.5) = 0.6 + 0.75 = 1.35
6.4 ni 2.0 ga bo‘ling, natijani 0.5 ga ko‘paytiring.
(6.4 ÷ 2.0) × 0.5 = 3.2 × 0.5 = 1.6
2.5 dan 0.9 ni ayiring, natijaga 3.1 ni qo‘shing.
(2.5 - 0.9) + 3.1 = 4.7
5.2 ni 0.4 ga ko‘paytiring, natijani 1.5 ga bo‘ling.
(5.2 × 0.4) ÷ 1.5 = 2.08
(1.6 × 3.5) + (2.2 × 0.8) ni hisoblang
(1.6 × 3.5) + (2.2 × 0.8) = 5.6 + 1.76 = 7.36
(0.5 × 2.0) + (1.5 × 0.6) ni hisoblang, natijani 2.0 ga bo‘ling
((0.5 × 2.0) + (1.5 × 0.6)) ÷ 2.0 = (1.0 + 0.9) ÷ 2.0 = 1.9 ÷ 2.0 = 0.95
4.8 ni 2.0 ga bo‘ling, natijani 1.2 ga ko‘paytiring, natijaga 2.4 ni qo‘shing
((4.8 ÷ 2.0) × 1.2) + 2.4 = (2.4 × 1.2) + 2.4 = 2.88 + 2.4 = 5.28
(3.4 × 2.0) - (0.6 × 1.3) ni hisoblang.
(3.4 × 2.0) - (0.6 × 1.3) = 6.8 - 0.78 = 6.02
(1.2 × 3) - 2.4 ni hisoblang
(1.2 × 3) - 2.4 = 1.2
(0.6 × 2.0) + (4.2 ÷ 1.4) ni hisoblang.
(0.6 × 2.0) + (4.2 ÷ 1.4) = 1.2 + 3.0 = 4.2
(4.5 × 1.2) - (3.6 ÷ 1.2) ni hisoblang.
(4.5 × 1.2) - (3.6 ÷ 1.2) = 5.4 - 3.0 = 2.4
5.6 ni 0.8 ga ko‘paytiring, natijani 1.4 ga bo‘ling, natijaga 3.0 ni qo‘shing.
((5.6 × 0.8) ÷ 1.4) + 3.0 = (4.48 ÷ 1.4) + 3.0 = 3.2 + 3.0 = 6.2
(1.2 × 2.5) - (0.6 × 1.4) ni hisoblang.
(1.2 × 2.5) - (0.6 × 1.4) = 3.0 - 0.84 = 2.16
(1.2 × 3.5) - (0.5 × 1.8) ni hisoblang.
(1.2 × 3.5) - (0.5 × 1.8) = 4.2 - 0.9 = 3.3
((3.5 × 1.2) - (1.8 ÷ 0.6)) + (2.4 × 0.8) ni hisoblang.
((3.5 × 1.2) - (1.8 ÷ 0.6)) + (2.4 × 0.8) = (4.2 - 3.0) + 1.92 = 1.2 + 1.92 = 3.12
(0.5 × 4.0) + ((2.4 ÷ 0.8) × 1.1) ni hisoblang.
(0.5 × 4.0) - ((2.4 ÷ 0.8) × 1.1) = 2.0 - (3.0 × 1.1) = 2.0 - 3.3 = -1.3
((5.2 ÷ 0.8) × 1.5) - (0.7 × 3.2) ni hisoblang.
((5.2 ÷ 0.8) × 1.5) - (0.7 × 3.2) = (6.5 × 1.5) - 2.24 = 9.75 - 2.24 = 7.51
(1.8 × 1.5) - ((2.4 ÷ 1.2) × 0.5) ni hisoblang.
(1.8 × 1.5) - ((2.4 ÷ 1.2) × 0.5) = 2.7 - (2.0 × 0.5) = 2.7 - 1.0 = 1.7
