Misollarni yeching.
138 • 4 + 204 : 4 = 603 c) 345 : 5 + 203 • 2 = 475
800 – 225 • 2 + 100 = 450 d) 950 – 328 : 4 + 125 = 993
2. Taqqoslang.
a) 3 l 200 g > 420 g c) 9 m 60 cm = 960 cm
b) 5 l 500 g < 6 l d) 10 m 80 cm > 980 cm
3. Tenglamalarni yeching.
x + 450 = 675 586 – x = 120
x = 675 – 450 x = 586 - 120
x = 225 x = 466
Tekshirish: Tekshirish:
225 + 450 = 675 586 – 466 = 120
675 = 675 120 = 120
x • 4 = 115 + 221 x : 6 = 435 – 300
x • 4 = 336 x : 6 = 135
x = 336 : 4 x = 135 • 6
x = 84 x = 810
Tekshirish: Tekshirish:
84 • 4 = 115 + 221 810 : 6 = 435 – 300
336 = 336 135 = 135
4. Berilgan kesmaning chorak qismini toping.
Javob: 60 cm
5. Berilgan ma’lumotlardan foydalangan holda aprel oyi davomida necha kun quyoshli, necha kun bulutli va necha kun yomg‘irli bo‘lganini aniqlang.
Quyoshli: 12 kun; Bulutli: 10 kun; Yomg‘irli: 8 kun.
