Ulushga ko`ra sonni toping.
1. Bir qop guruh teng 5 qismga bo`lindi, har bir qism 10 kg keladi. Barcha guruh
necha kilogramm?
Agar sonning 5dan 1 qismi ma’lum bo`lsa, sonni qanday topish kerak?
2. Agar barcha tomoshabinlarning 1 %i 7 kishini tashkil etsa, kinoteatrda nechta
tomoshabin bo`lgan?
1 – 7
100 – x
1 x = 7 100
X = 700
Javob: 700 kishi

sonlarini `osib borish tartibida yozing.
4. Tenglamani yeching.
1)
(12 – x) 5 = 30
12 – x = 30 : 5
12 – x = 6
x = 6
2)
x : 3 + 480 = 600
x : 3 = 600 – 480
x : 3 = 120
x = 120 3
x = 360
5. Hisoblang.
401 (30596 – 29596) + 595000: (312 +538) -226896 : 87 = 399092
1) 30596 – 29596 = 1000
2) 401 1000 = 401000
