✔ 最佳答案
設原來的除數是x69 = 6x+3
66 = 6x
11 = x
之後,
將96/11=8....8
正確的商應是8

先求除數是????
69-3=66
66/6=11
Then you can find that the result for this question is 8.....8.
這是用倒推法.
69-3=66
66/6=11
Then you can find that the result for this question is 8.....8.
這是用倒推法.

係8
設除數係m
先前用69做被除數, 69 = 6m + 3
得 m = 11
用96 除 11 得商8
設除數係m
先前用69做被除數, 69 = 6m + 3
得 m = 11
用96 除 11 得商8

69減3除6=11
再把96除11=8.....8
再把96除11=8.....8

69/x=6...3
x=11
96/11=8...8
正確的商8
x=11
96/11=8...8
正確的商8

let x be 用來除的數
69/x=6...3
66/x=6
x=11
96/11=8...8
正確的商應是8.
69/x=6...3
66/x=6
x=11
96/11=8...8
正確的商應是8.
