To calculate 20% off £45, we first need to determine what 20% of £45 is. Percentages represent a portion of a whole, expressed as a fraction of 100. Thus, 20% corresponds to 20/100 or 0.20.
Here’s a step-by-step breakdown of the calculation:
Convert the percentage to a decimal:
20%=0.20Multiply the original amount by this decimal:
£45×0.20=£9This tells us that 20% of £45 is £9, which represents the discount amount.
To find the final price after applying the discount, we subtract the discount from the original price:
£45−£9=£36Therefore, when you apply a 20% discount to £45, the final price is £36. This method can be used for calculating any percentage discount on any amount, making it a valuable skill for shopping, budgeting, and various real-life financial situations.
