下列算式中的余数可能是几?
1.( 8) ÷7 = ( 1).( 1)
.(9 ) ÷7 = ( 1).(2 )
.( 10) ÷7 = (1 ).( 3)
.( 11) ÷7 = (1 ).( 4)
.( 12) ÷7 = ( 1).( 5)
.( 13) ÷7 = (1 ).( 6)
.( 15) ÷7 = ( 2).( 1)
.(16 ) ÷7 = ( 2).(2 )
2.( 73) ÷9 = 8.(1 )
( 74) ÷9 = 8.(2 )
(75 ) ÷9 = 8.( 3)
(76 ) ÷9 = 8.( 4)
( 77) ÷9 = 8.(5 )
( 78) ÷9 = 8.(6 )
( 79) ÷9 = 8.( 7)
( 80) ÷9 = 8.( 8)
3. ( 9) ÷8= ( 1).(1 )
( 10) ÷8= ( 1).( 2)
( 11) ÷8= (1 ).( 3)
( 12) ÷8= ( 1).(4 )
( 13) ÷8= ( 1).( 5)
( 14) ÷8= ( 1).( 6)
( 15) ÷8= ( 1).( 7)
4. 39 ÷4=( 9).( 3)
余数一定要小于除数
