30% of 60 is 18. Three tenths: 0.3 × 60 = 18. Ten percent is effortless: 10% of 60 = 6, and 6 × 3 = 18. Because sixty is three twenties, you can triple a familiar slice—30% of 20 is 6, so 6 × 3 = 18. It is also twice 30% of 30 (9). On the same base, 20% of 60 is 12 and 25% of 60 is 15, so thirty percent sits three units above the quarter—easy to remember on a minute hand or a sixty-item tally.
30% off £60 means the discount is £18 and you pay £42 before extras. If someone asks only for thirty percent of sixty, the answer is 18, not forty-two—forty-two is what remains after the reduction.
Double the base to one hundred twenty: 30% of 120 is 36, exactly 2 × 18. Five less on the base drops the slice by one and a half: 30% of 55 is 16.5, and adding five back toward sixty adds 1.5 to reach 18—a quick bridge if you already had fifty-five in your head.
One third of sixty is 20, which is two units above the eighteen you get at exactly thirty percent. “About a third” in conversation is still not the same as thirty percent on this base.
If £60 is reduced by 30%, the reduction is £18 and you pay £42 (before other charges).

Formula used: (percentage ÷ 100) × number

Full formula: (30 ÷ 100) × 60 = 18
Ten-percent bridge: 10% of 60 = 6; triple it → 18. Same as 60 × 3 ÷ 10 if you multiply before dividing.
Sixty is a multiple of ten and of six, so each ten-percent band is a whole 6 and thirty percent stacks three bands into 18 with no fractions. That is why exam timers, video runtimes, and “sixty minutes on the clock” examples love this pair—the arithmetic stays in integers end to end.
Seventy percent remains after a thirty-percent cut: 60 − 18 = 42, or 0.7 × 60 = 42. If you see forty-two pounds left from a sixty-pound list under a thirty-percent headline, you can read the eighteen-pound markdown in reverse.
Default: 10% of 60 = 6, then 6 × 3 = 18.
From 25% of 60 = 15, add 5% of 60 (3) → 18. From 15% of 60 = 9, double the rate mentally → 18.
