30% of 1200 is 360. Decimals agree: 0.30 × 1200 = 360. Twelve hundred is 12 × 100, so thirty percent is twelve thirties: 30 × 12 = 360. The tenth route is smooth: 1200 ÷ 10 = 120, then 120 × 3 = 360. Notice 30% of 600 is 180; doubling the base doubles the slice to 360. On the same total, 25% of 1200 is 300 and 20% of 1200 is 240; adding one 10% of 1200 (120) steps you from two-forty to three-sixty. Doubling 15% of 1200 (180) checks out too.
30% off £1200 means £360 off and you would usually pay £840 before extras. If the wording asks only for thirty percent of twelve hundred, the answer is 360, not the post-discount total.
Same rate on round neighbours: 30% of 1000 is 300, so two hundred more on the base adds 60 at this percentage (300 + 60 = 360). 30% of 1100 is 330; another hundred on the base adds thirty. 30% of 1500 is 450, ninety above three-sixty—three hundred more on the base at 30% adds ninety.
Scale check: 30% of 12000 = 3600. Misplacing a zero turns 360 into 3600 when the true total was only twelve hundred.
If £1200 is reduced by 30%, the reduction is £360 and you pay £840 (before other charges).

Formula used: (percentage ÷ 100) × number
Step 1: Convert 30% → 0.30 (divide 30 by 100).
Step 2: Multiply: 0.30 × 1200 = 360.
Full formula: (30 ÷ 100) × 1200 = 360
Tenths: 10% of 1200 = 120; 120 × 3 = 360. Or twelve times thirty from the hundreds.
The base is a multiple of 100 and 12, so “per hundred” chunks and tenths both stay whole numbers: 120, 360, 840 arrive without rounding noise. That is why twelve hundred appears often when examples need a friendly thirty-percent story.
After removing thirty percent, 70% remains: 1200 − 360 = 840, or 0.70 × 1200 = 840. Pairing 360 with 840 matches the usual discount layout—amount off versus amount still due—on a simple model.
50% of 1200 is 600; thirty percent is three-fifths of that half—more steps than tripling one-twenty, but a valid cross-check.
