| b |
| a |
则有
| b |
| a+6 |
| 5 |
| 14 |
| 5×(a+6) |
| 14 |
| b |
| a−2 |
| 7 |
| 18 |
| 7×(a−2) |
| 18 |
因此
| 5(a+6) |
| 14 |
| 7×(a−2) |
| 18 |
14×7×(a-2)=18×5(a+6),
98a-196=90a+540,
8a=736,
a=92;
b=
| 5×(92+6) |
| 14 |
所以原分数为
| 35 |
| 92 |
故答案为:
| 35 |
| 92 |
| 5 |
| 14 |
| 7 |
| 18 |
| b |
| a |
| b |
| a+6 |
| 5 |
| 14 |
| 5×(a+6) |
| 14 |
| b |
| a−2 |
| 7 |
| 18 |
| 7×(a−2) |
| 18 |
| 5(a+6) |
| 14 |
| 7×(a−2) |
| 18 |
| 5×(92+6) |
| 14 |
| 35 |
| 92 |
| 35 |
