1-mashg’ulot Mavzu: Cho‘tlar. Uch xonali sonlarni cho‘tga solish. 320+430, 860-250 ko‘rinishdagi misollarni yechish

2-variant

1. Amallarni bajaring.

6094. 
      • 14 - 367 710: (51 • 10)=
      

6094•14=85316

51•10=510

367710:510=721

85316-721=84595

2. Tenglamani yeching.

x•32 + 100 = 420 12 • (x - 200) = 24 612

x•32=420-100 x-200= 24612:12

x•32=320 x-200= 2051

x= 320:32 x=2051+200

x=10 x=2251

3. Bo'lishni bajaring va natijani ko'paytirish yordamida tekshiring.

3640 : 40= 91 5 625 : 25= 225

4. Masalani yeching.

Omborda 80 kg li qoplarda 6 400 kg un va 60 kg li qoplarda 3 600 kg guruch bor. Ombordagi un qoplari guruch qoplariga qaraganda nechta ko'p?

6400:80=80 3600: 60=60

80-60=20 Javob: 20 ta ko’p

Uyga vazifa: takrorlash.
