Вычислите частное по образцу : а) 400: 80=(400: 10): (80: 10)=40: 8=; б) 800: 400; в) 16000: 800 г) 300: 50 0

Б) 800:400 = (800:10):(400:10) = (80:10):(40:10)=8:4 =2
В) 16000:800=(16000:10):(800:10)=(1600:10):(80:10)=160:8=20
Г)300:500 =(300:10):(500:10) =(30:10):(50:10) = 3:5 = 0.6
    300:50 = (300:10):(50:10)= 30:5 =6
