两个数相除，商是3，余数是20，被除数、除数、商与余数的和是243，被除数是多少?除数是多少？

Question

如题所述

Answer 1

1、被除数÷除数=3……… 20；若减去20，被除数是除数的3倍，除数1份，被除数3份，一共（1＋3）份。

2、被除数＋除数＋3＋20=243

3、被除数与除数的和：243－3－20=220

4、除数：（220－20）÷（1＋3）=50

5、被除数：220－50=170 或 50×3＋20=170

Answer 2

243-20=223 223-3=220 220-20=200 200÷（3+1）=50 50×3=150 150+20=170
被除数是170 除数是50

Answer 3

被除数170，除数50

Answer 4

243-20-3=220
220-20=200
3+1=4
200/4=50
50*3+20=170
