8-nazorat ishi
I variant
1. Amallarni bajaring:
39 · 10 7 · 100 780 : 10 900 : 100
2. Bo‘sh kataklar o‘rniga >, < yoki = belgilarini qo‘ying:
18 · 10 2 · 100 220 : 10 370 : 10
9 · 100 90 · 10 800 : 100 600 : 100
3. Tenglamalarni yeching va javoblarini tekshiring:
10 · x = 820 x · 100 = 500 x : 10 = 54
4. O‘tkir, to‘g‘ri va o‘tmas burchaklarni chizing.
5. 10 ta rangli qalam 500 so‘m turadi. Shunday 4 ta qalam necha so‘m turadi?
II variant
1. Amallarni bajaring:
54 · 10 3 · 100 320 : 10 700 : 100
2. Bo‘sh kataklar o‘rniga >, < yoki = belgilarini qo‘ying:
27 · 10 2 · 100 460 : 10 510 : 10
7 · 100 70 · 10 500 : 100 400 : 100
3. Tenglamalarni yeching va javoblarini tekshiring:
10 · x = 740 x · 100 = 900 x : 10 = 34
4. Teng tomonli, teng yonli va turli tomonli uchburchaklarni chizing.
5. 10 ta o‘chirg‘ich 1000 so‘m turadi. Shunday 2 ta o‘chirg‘ich necha so‘m turadi?
