10 − 8.2 = 1.8 remaining

How to calculate it

Method 1: multiply directly

10 × 82% = 10 × 82 ÷ 100 = 820 ÷ 100 = 8.2. 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 10 is 0.1, so 82% is 0.1 × 82 = 8.2. 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: 10 × 82 ÷ 100 = 8.2. By hand, find 1% first (0.1) and multiply by 82; the same formula works above 100%, where the result exceeds the base.

Start with 10% (shift the decimal point one place left — 10% of 10 is 1), then combine: 20% is double, 5% is half of that, 15% is 10% plus 5%. Split 82% into 80% plus 2% and add the two parts. With practice, any two-digit base becomes mental math.

Use "part ÷ whole × 100%": 8.2 ÷ 10 × 100% = 82%. This is the inverse of "find a percentage of a number" — the same relationship, part = whole × percentage, read backwards.

82% = 82 ÷ 100 = 0.82. The percent sign itself means "divide by 100": removing it shifts the decimal two places left, adding it shifts two places right.
