sinf uchun matematikadan nazorat ishi : Misollarni yeching

4 – sinf uchun matematikadan nazorat ishi :

1) Misollarni yeching;

3256 * 67 = 3862*45 = 8596*26 + 87906 = 12964 + 235*57 – 22745 =

8532* 12 = 7589*34 = 5739*32 + 25974 = 36485 - 568*6 + 4786 =

9076*17 = 6409*28 = 9631*22 + 52238 = 58937 + 912* 25 -23869 =

2 )Masalani yeching ;

1— poyezdda 17 vagon har birida 5 ta yo'lovchidan, 2—poyezdda esa 14 vagon har birida 7 ta yo'lovchidan iborat . Hammasi bo’lib 2 poyezdda necha yo'lovchi mavjud ekanligini toping.

3) Ifodani taqqoslang ;

1236+8947 \ 8964-4398 25874+9853 \ 91776+1973

56723+15876 \ 89674-14587 3894 * 8 \ 9631 * 3

953 * 58 \ 526 * 57 2894 * 9 \ 6972 * 4
