Nazorat ishlarini o‘tkazish yuzasidan tavsiyalar

JAVOBLAR:

I variant

1. Amallar 39 · 10= 390 7 · 100 =700 780 : 10= 780 900 : 100 = 9

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 10 · x = 820 x=82 x · 100 = 500 x=5 x : 10 = 54 x=540

4. O‘tkir, to‘g‘ri va o‘tmas burchaklarni chizing.

5. 500 : 10 = 50so`m 50 * 4 = 200so`m turadi.

II variant

1. Amallar 54 · 10 =540 3 · 100 = 300 320 : 10= 32 700 : 100 = 7

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. Tenglamalar 10 · x = 740 x=74 x · 100 = 900 x=9 x : 10 = 34 x=340

4. Teng tomonli, teng yonli va turli tomonli uchburchaklarni chizing.

5. 1000 : 10 = 100so`m 100 * 2 = 200so`m turadi
