25% of 500 is 125. Treat twenty-five percent as one quarter: 500 ÷ 4 = 125. The decimal route matches: 0.25 × 500 = 125. Because 500 = 5 × 100, you can also read the quarter as five copies of twenty-five: 5 × 25 = 125—twenty-five from each hundred in the total. On the same base, 20% of 500 is 100 and 30% of 500 is 150, so the quarter sits exactly halfway between those two round figures at 125. If you like thinking in halves of a thousand, note that 500 is half of 1000; a quarter of five hundred is therefore half of a quarter of a thousand (250 ÷ 2 = 125), which is a useful cross-check when invoices or stock counts jump between 500 and 1000.
Read 25% off £500 as “subtract £125,” leaving £375 before delivery or tax. If the wording is strictly “what is twenty-five percent of five hundred?” the answer is 125, not three hundred and seventy-five—375 is what remains after you remove the quarter, not the quarter itself.
Neighbouring bases sharpen the picture. 25% of 450 is 112.5; adding fifty to the base adds exactly twelve point five to the quarter, landing on 125. 25% of 600 is 150, twenty-five above your figure here. 25% of 400 is 100, so each extra hundred on the base lifts the quarter by twenty-five when you stay on twenty-five percent.
Scale-check: 25% of 5000 = 1250. If someone quotes five thousand but you mentally anchored on five hundred, multiplying the quarter by ten catches the slip before it hits a budget line.
If £500 is reduced by 25%, the reduction is £125 and you pay £375 (before other charges).

Formula used: (percentage ÷ 100) × number
Step 1: Convert 25% → 0.25 (or think “one quarter”).
Step 2: Multiply: 0.25 × 500 = 125.
Full formula: (25 ÷ 100) × 500 = 125
Quarter shortcut: 500 ÷ 4 = 125. Hundred-wise check: 5 × (25% of 100) = 5 × 25 = 125.
Five hundred divides cleanly by four, so the quarter is a whole 125 with no trailing decimals—unlike 25% of 450 (112.5). That makes the figure easy to reuse in payroll slices, inventory batches, and currency without rounding arguments.
The three-quarter remainder is 375 (500 − 125 or 0.75 × 500). In “25% off” language on a five-hundred-pound subtotal, 375 is the amount people pay; in “what is 25% of 500?” language, 125 is the slice they are asking for. Keeping those two numbers distinct prevents the common mix-up between discount amount and price after discount.
25% of 250 is 62.5; doubling both base and quarter lands on 125 for five hundred—a quick sanity check if two-fifty is easier to hold in short-term memory than five hundred.
Fastest for many: 500 ÷ 4 = 125.
From 20% of 500 = 100, add 5% of 500 (25) to reach the quarter: 100 + 25 = 125. That five-percent step is often quicker than re-running the full quarter when you already have one-fifth in mind.
Example 1: Twenty-five percent off a £500 appliance
The markdown is £125 and you pay £375 if nothing else stacks.
Example 2: Five hundred units, quarter allocated to a pilot
125 units go to the trial run and 375 stay in general stock on a strict one-quarter rule.
Example 3: A £500 project fee, 25% upfront
The first invoice is £125; the wording “25% of the fee” refers to that slice, not the £375 still to bill.
Example 4: Tenfold base
On 5000, 25% is 1250. Dropping a zero from the base but keeping the quarter fixed is a frequent reporting mistake—use the scale-check when tables jump an order of magnitude.
25% of 500 is 125.
Divide 500 by 4, multiply 500 by 0.25, or take five times 25% of 100 (25 + 25 + 25 + 25 + 25).
Removing the 25% portion (125) from 500 leaves 375.
Because 500 is divisible by 4, one quarter comes out exactly with no fractional part.
