Well, 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.
Oh, dude, the missing number is 7. It's like a math puzzle, but not the fun kind, more like the kind that makes you question why you're even trying to solve it. But hey, at least now you know the answer!
The missing number in the sequence 100, 81, 63, 30, 15 is 6. The pattern involves subtracting decreasing consecutive prime numbers: 19 (100-19=81), 18 (81-18=63), 13 (63-13=50), and 15 (30-15=15).
15 percent of 100 is 15, so 15 percent of 200 is 30!
1, 2, 3, 5, 6, 10, 15, 30 None missing.
Find the difference between the two numbers and divide that into the smaller number. Multiply that total by 100. Example: Percentage increase from 30 to 45. 45 - 30 = 15 15/30 = 0.5 0.5 x 100 = 50% 30 to 45 is a 50% increase.
50/100 x 30/100 = 15%
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
