Question

64 is 0.4% of what number ? Use pencil and paper would you expect the answer to be a lot less than 64

Answer 1

64 is 0.4% of 16000. To find this, we set up an equation and solve for the unknown number, showing that the answer is larger than 64.

Step-by-step explanation:

To find the number that 64 is 0.4% of, we can set up the equation where x represents the unknown number we're seeking: 0.4% of x = 64.

First, we convert the percentage to a decimal by dividing 0.4 by 100, which gives us 0.004.

Now our equation is 0.004 * x = 64.

To solve for x, we divide both sides of the equation by 0.004:

x = 64 / 0.004

x = 16000

So, 64 is 0.4% of 16000.

Given the small percentage, we would expect the answer to be much larger than 64, not less.
