Question

Вычислите частное по образцу
a)400:80=(400:10):(80:10)=40:8=
800:400
6400:1600
16000:800
20000:4000
300:50
2000:500

Answer 1

1.800÷400=(800÷10)÷(400÷10)=80÷40;
2.6400÷1600=(6400÷10)÷(1600÷10)=640÷160;
3.16000÷800=(16000÷10)÷(800÷10)=1600÷80;
4.20000÷4000=(20000÷10)÷(4000÷10)=2000÷400;
5.2000÷500=(2000÷10)÷(500÷10)=200÷50;
6.300÷50=(300÷10)÷(50÷10)=30÷5.
