2 | ( | h | − | 55 100 | ) | ÷ | 3 | = | 40 100 |
方程左边 = | 2 3 | ( | h | − | 55 100 | ) |
2 3 | ( | h | − | 55 100 | ) | = | 40 100 |
方程左边 = | 2 3 | h | − | 2 3 | × | 55 100 |
= | 2 3 | h | − | 11 30 |
2 3 | h | − | 11 30 | = | 40 100 |
2 3 | h | = | 40 100 | + | 11 30 |
2 3 | h | = | 23 30 |
h | = | 23 30 | ÷ | 2 3 |
= | 23 30 | × | 3 2 |
= | 23 10 | × | 1 2 |
h | = | 23 20 |
h | = | 1.15 |
