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
Спасибо
