How do you find out the percentage of a number?
100% is the whole number. 4 is 100% of 4. 2 is 50% of 4. 1 is 25% of 4. See a pattern? 2 is half of 4. 50 is half of 100. 1 is one fourth of 4. 25 is one fourth of 100. Percentage is basically taking a number, dividing it by the maximum possible number, and multiplying it by 100. It's like finding the fraction/decimal and multiplying it by 100. Eg. if you get 46 out of 50 in a test, to find your percentage, you divide 46 by 50 and multiply by 100: 46/50=0.92 0.92x100%=92% (note, you should put '%' behind the 100 to show that you're finding percentage) Tips: Incidentally, 46 is exactly half of 92. When your maximum possible number is a factor of 100, you can just multiply your mark by the other factor. In other words, since 50x2=100, to find the percentage of 46/50, just take 46x2. So if you have for example 22/25, just multiply 22 by 4 to get the percentage (88%) since 25x4=100. More tedious numbers such as 43/45 would require the longer method of dividing 43 by 45 and multiplying by 100. Of course if the maximum possible number is 100 then your life is easy, since you don't need to do anything. 80/100 is just 80%. When you have percentages like 200%, it means double the maximum possible number. Eg. 200% of 4 is 8. 500% of 4 is 20, and so on. If you want to find 150% of 4, divide 150 by 100 and multiply by 4. 150% of 4=(150/100)x4=6 This is basically the same thing as taking 100% of 4 and 50% of 4 and adding them together: 100% of 4 + 50% of 4 = 4 + 2 = 6 The more you play with percentages, the more patterns you'll see, and you'll find lots of shortcuts. sorry it's so long x_x
What is importance of DNA copying in reproduction?
If DNA wasn't copied before cell reproduction, after the cells divide they would only have half the DNA that the original cell had. And since we need all our DNA to tell the rest of the cell how to carry out all functions, with only half the DNA, a cell would shut down.
