15% of 130 is 19.5. To calculate this, you can multiply 15/100 with 130, which gives (15/100)130 = (15130)/100 = 1950/100 = 19.5. Alternatively, you can use the formula (Whole × Percent)/100 = Part, where the whole is 130, the percent is 15, and the part is what we want to find. Plugging in these values gives (130 × 15)/100 = 19.5.
