4:5

Do you want me to interpret or manipulate the ratio 4:5? Here are the key facts and quick uses: - As a fraction: 4:5 = 4/5. - As a decimal: 4/5 = 0.8. - As a percentage: 80%. - If 4:5 is the ratio of two parts of a whole: - Total parts = 4 + 5 = 9. - The 4-part portion = 4/9 of the total. - The 5-part portion = 5/9 of the total. - Example: If the total is 180 units, then: - 4-part share = (4/9) × 180 = 80 - 5-part share = (5/9) × 180 = 100 - If you have A:B = 4:5 and A + B = T, then: - A = (4/9) × T - B = (5/9) × T - Scaling: 4:5 is equivalent to 8:10, 12:15, etc. If you multiply both sides by k, you get 4k : 5k. How would you like to apply this to a problem? If you have a specific exam question, share it and I’ll work through it.
