What is 40 percent of 10 dollars?

Answer 1

To quickly calculate this in your head, start by taking 10% of the value. This is done by simply moving the decimal place 1 to the left. In this example, 10% of $10.00 is $1.00. Now, we want 40% which is 4 times that amount (4 * 10% = 40%). So $1.00 * 4 = $4.00.
