25% of 600 is 150. One quarter of six hundred: 600 ÷ 4 = 150. Decimals match: 0.25 × 600 = 150. Because 600 = 6 × 100, you can stack six copies of twenty-five: 6 × 25 = 150—the quarter taken from each hundred in the total. On the same base, 20% of 600 is 120 and 30% of 600 is 180, so twenty-five percent lands exactly halfway between those two at 150. Another framing: six hundred is half of twelve hundred, and a quarter of twelve hundred is three hundred—half of that is 150, which is the same quarter of six hundred without touching a calculator.
Read 25% off £600 as “take off £150,” leaving £450 before extras. If the question is only “what is twenty-five percent of six hundred?” the answer is 150, not four hundred and fifty—the latter is what is left after the discount, not the discount itself.
Nearby totals: 25% of 500 is 125; adding a hundred to the base adds twenty-five to the quarter, which brings you to 150. 25% of 650 is 162.5, so fifty extra on the base lifts the quarter by twelve point five. 25% of 300 is 75; doubling both base and quarter checks out: 75 × 2 = 150.
Scale-check: 25% of 6000 = 1500. If a spreadsheet row shows six thousand but you anchored on six hundred, scaling the quarter by ten avoids quoting 150 when 1500 is correct.
If £600 is reduced by 25%, the reduction is £150 and you pay £450 (before other charges).

Formula used: (percentage ÷ 100) × number
Step 1: Convert 25% → 0.25 (or think “one quarter”).
Step 2: Multiply: 0.25 × 600 = 150.
Full formula: (25 ÷ 100) × 600 = 150
Quarter shortcut: 600 ÷ 4 = 150. Hundred-wise check: 6 × (25% of 100) = 6 × 25 = 150.
Six hundred divides by four with no remainder, so the quarter is a whole 150—handy for invoices, headcount splits, and stock lines where fractions would slow people down. Contrast that with 25% of 650 (162.5), where the same percentage suddenly introduces a half-unit you must explain.
The three-quarter remainder is 450 (600 − 150 or 0.75 × 600). In retail wording, 450 is the post-discount subtotal on six hundred at twenty-five percent off; 150 is the slice the percentage question names when it asks for the portion, not the remainder.
25% of 750 is 187.5. The base rose by 150 from six hundred to seven fifty, and the quarter rose by 37.5—a reminder that once you leave round multiples of four, the same percentage stops landing on whole numbers.
Fastest for many: 600 ÷ 4 = 150.
From 20% of 600 = 120, add 5% of 600 (30): 120 + 30 = 150. That last step is often faster than re-deriving the quarter from scratch when a twenty-percent figure is already on the page.
Example 1: Twenty-five percent off a £600 laptop
The saving is £150 and you pay £450 if nothing else applies.
Example 2: Six hundred call minutes, quarter for outbound
On a simple split, 150 minutes are tagged outbound and 450 stay in the general pool—same numbers as pounds, different unit.
Example 3: Ten hours on the clock as 600 minutes
A quarter of that block is 150 minutes—two and a half hours—mirroring the percentage result on the raw six hundred.
Example 4: Tenfold base
On 6000, 25% is 1500. Misreading the magnitude of the base is a common way to be wrong by exactly one decimal place in reports.
25% of 600 is 150.
Divide 600 by 4, multiply 600 by 0.25, or take six times 25% of 100 (25 + 25 + 25 + 25 + 25 + 25).
Removing the 25% portion (150) from 600 leaves 450.
Because 600 is divisible by 4, one quarter comes out exactly with no fractional part.
