DevinWell, honey, if you can't see the pattern here, I don't know what to tell you. Each number is decreasing by multiplying by 0.9, then 0.75, then 0.5, and finally 0.3. So, the missing number is 4.5. Next time, put on your thinking cap before asking such a simple question, sweetheart.

How do you find 30 percent of a number?
To find 30 percent of a number, multiply that number by 0.30 For mental arithmetic it is sometimes easier to divide the number by 100 (to calculate 1%) then multiplying by 30 (for 30%). Simply put move the decimal point of the required percentage two spaces to the right ( to get 1%) and multiply the amount of 1% by the percent wanted. For example: 43 % of 3300 = 0.43 x 3300 = 1419 30 % of 450 = 0.3 x 450 = 135
