20% of 300 is 60. One fifth of three hundred is sixty: 300 ÷ 5 = 60. Decimals agree: 0.2 × 300 = 60. 300 = 3 × 100, and 20% of 100 is 20, so three twenties make 60. 10% of 300 is 30; doubling gives 60 again. Because 300 = 250 + 50, add 20% of 250 (50) and 20% of 50 (10): 50 + 10 = 60. On the same base, 25% of 300 is 75 and 30% of 300 is 90—so twenty percent is the whole-number fifth below those neighbours.
Read 20% off £300 as “remove £60,” leaving £240 before extras. If someone asks for twenty percent of three hundred—fee, slice, or allocation—the answer is 60, not two hundred and forty. The remainder only matches “after discount” wording.
Compare bases: 20% of 275 is 55 and 20% of 350 is 70, so three hundred’s fifth sits between those at 60. 20% of 250 is 50; adding fifty to the base adds ten to the fifth (50 + 10 = 60). 20% of 200 is 40, so moving from two hundred to three hundred adds one hundred to the base and twenty to the fifth (40 + 20 = 60).
Multiply the base by ten: 20% of 3000 is 600. If a three-hundred-pound subtotal becomes three thousand on the same percentage rule, the slice scales the same way—watch the decimal so you do not report 60 or 6000 by mistake.
If £300 is reduced by 20%, the reduction is £60 and you pay £240 (before other charges).

Formula used: (percentage ÷ 100) × number
Step 1: Convert 20% → 0.2.
Step 2: Multiply: 0.2 × 300 = 60.
Full formula: (20 ÷ 100) × 300 = 60
Fifth shortcut: 300 ÷ 5 = 60. Triple-century: 3 × (20% of 100) = 3 × 20 = 60.
Three hundred is 3 × 100, so twenty percent scales as three times the one-hundred row—ideal for quick benchmarking against “per hundred” thinking.
Against 20% of 150 (30): doubling the base from one-fifty to three hundred doubles the fifth (30 × 2 = 60).
Fastest: 300 ÷ 5 = 60.
From 25% of 300 = 75, subtract 5% of 300 = 15 to land on sixty—useful if quarters come first mentally.
Example 1: Twenty percent off a £300 fee
The markdown is £60 and you pay £240 if nothing else stacks.
Example 2: Three-hundred-unit batch
If a 20% quality hold applies, 60 units are ring-fenced and 240 are free to ship under a strict rule.
Example 3: Budget line
Allocating 20% of a £300 sub-budget means £60 for that line and £240 notionally elsewhere—not the other way round unless the wording says “after discount.”
Example 4: Tenfold check
20% of 3000 is 600. If you see 60 or 6000 on the scaled row, revisit the percent-to-decimal step.
20% of 300 is 60.
Multiply 300 by 0.2, divide 300 by 5, or double 10% of 300 (30 → 60).
20% off 300 is a reduction of 60, leaving 240.
