14,976:0,72

I think you might mean a ratio with a decimal comma, i.e., 14.976 : 0.72.

• Clear decimals: multiply by 1000 to remove decimals -> 14976 : 720
• GCD(14976, 720) = 144
• Divide: 14976/144 = 104, 720/144 = 5
• Simplified ratio: 104 : 5
• Decimal form: 104/5 = 20.8

So, 14.976 : 0.72 = 104 : 5 = 20.8.

If instead you meant 14,976 (fourteen thousand nine hundred seventy-six) to 0.72, the result would be 20800 : 1 (i.e., 20800). Let me know which format you intended.
