20 − 2.4 = 17.6 remaining

How to calculate it

Method 1: multiply directly

20 × 12% = 20 × 12 ÷ 100 = 240 ÷ 100 = 2.4. A percentage literally means "per hundred", so multiplying the base by the percentage and dividing by 100 gives the part.

Method 2: find 1% first, then scale

1% of 20 is 0.2, so 12% is 0.2 × 12 = 2.4. Using 1% as a stepping stone is the fastest mental route when you do not remember the formula.

FAQ

The formula is "base × percentage ÷ 100". Plugging in: 20 × 12 ÷ 100 = 2.4. By hand, find 1% first (0.2) and multiply by 12; the same formula works above 100%, where the result exceeds the base.

Start with 10% (shift the decimal point one place left — 10% of 20 is 2), then combine: 20% is double, 5% is half of that, 15% is 10% plus 5%. Split 12% into 10% plus 2% and add the two parts. With practice, any two-digit base becomes mental math.

Use "part ÷ whole × 100%": 2.4 ÷ 20 × 100% = 12%. This is the inverse of "find a percentage of a number" — the same relationship, part = whole × percentage, read backwards.

12% = 12 ÷ 100 = 0.12. The percent sign itself means "divide by 100": removing it shifts the decimal two places left, adding it shifts two places right.
