Twenty four to one (24:1) is a ratio used by some older 2 stroke motors, largely it seems to have been replaced with 25:1 or 50:1 these days. The ratio is not the easiest 2 stroke ratios to calculate.
To make it easier you can use the following old school reference chart.
Fuel (L) | Oil (mL) |

1 | 42 |
2 | 83 |
3 | 125 |
4 | 167 |

7.5 | 313 |
10 | 417 |
15 | 625 |
