30% of 600 is 180. As decimals, 0.30 × 600 = 180. Six hundred is 6 × 100, so thirty percent is six thirties: 30 × 6 = 180. The tenth route is smooth: 600 ÷ 10 = 60, then 60 × 3 = 180. Notice 30% of 300 is 90; doubling the base doubles the slice to 180. On the same total, 25% of 600 is 150 and 20% of 600 is 120; the jump from twenty to thirty percent is exactly 10% of 600 (60). Doubling 15% of 600 (90) lands on the same answer.
30% off £600 means £180 off and you would usually pay £420 before extras. If the question asks only for thirty percent of six hundred, the answer is 180, not the reduced total.
Same rate on round neighbours: 30% of 500 is 150, so another hundred on the base adds 30 (150 + 30 = 180). 30% of 400 is 120; two hundred more on the base at this rate adds 60. 30% of 720 is 216, thirty-six above one-eighty—one-twenty more on the base at 30% adds thirty-six.
Scale check: 30% of 6000 = 1800. Misplacing a zero turns 180 into 1800 when the spoken total was only six hundred.
If £600 is reduced by 30%, the reduction is £180 and you pay £420 (before other charges).

Formula used: (percentage ÷ 100) × number
Step 1: Convert 30% → 0.30 (divide 30 by 100).
Step 2: Multiply: 0.30 × 600 = 180.
Full formula: (30 ÷ 100) × 600 = 180
Tenths: 10% of 600 = 60; 60 × 3 = 180. Or six times thirty from the hundreds.
The base is a multiple of 100, 10, and 6, so tenths and “per hundred” chunks stay whole: 60, 180, 420 all arrive without rounding. That makes six hundred a favourite in worked examples when the goal is a tidy thirty-percent story.
After removing thirty percent, 70% remains: 600 − 180 = 420, or 0.70 × 600 = 420. Pairing 180 with 420 matches the usual discount picture—amount off versus amount still due—on a simple model.
60% of 600 is 360; thirty percent is exactly half of that six-tenths portion—another quick structural check.
Default: one tenth is 60; triple it → 180.
From 25% of 600 = 150, add 30 (five percent of six hundred) to reach 180.
50% of 600 is 300; thirty percent is three-fifths of that half—more steps than tripling sixty, but a valid verification.
Example 1: Thirty percent off a £600 holiday
The saving is £180 and you pay £420 if nothing else applies.
Example 2: Commission on a £600 sale
A 30% cut is £180; the simple “seller keeps before other fees” picture is £420 on a strict percentage model.
Example 3: Larger headline
30% of 750 is 225—useful when you outgrow six hundred but still want the same rate for comparison.
Example 4: Tenfold slip
On 6000, 30% is 1800. One wrong zero turns 180 into 1800.
30% of 600 is 180.
Find 10% of 600 (60) and multiply by 3, or add 30% of each of the six hundreds (30 × 6), or note that 30% of 300 is 90 and double it.
Removing the 30% portion (180) from 600 leaves 420.
60% of 600 is 360, and 30% is exactly half of that—180.
