The answer is 80. Below: three ways to calculate it, a mental shortcut, and the real-world contexts where this percentage shows up.
40% of 200 is 80.
A deep 40% discount on a 200-dollar item is common in end-of-season sales.
Divide the percent by 100 to convert it: 40 ÷ 100 = 0.4.
Multiply: 200 × 0.4 = 80.
40% means 40/100. So 40% of 200 is (40 × 200) ÷ 100.
Compute: 40 × 200 = 8000, then divide: 8000 ÷ 100 = 80.
No single elegant mental shortcut for 40% — but you can always split: 40% = (some 10%) + (some 5%) + (some 1%). Try 4×(10% of 200) plus 0×(1% of 200).
A discount is just a percentage subtracted from the original price. To find the final price, calculate the discount first, then subtract.
