Divide the total from Step 1 by the number of decimals in your set (as determined in Step 2). In this example, you would divide 5.79 by 4 to get 1.4475. This is the average for your set.

When comparing decimals, start in the tenths place. The decimal with the biggest value there is greater. If they are the same, move to the hundredths place and compare these values. If the values are still the same keep moving to the right until you find one that is greater or until you find that they are equal.

['To simplify a ratio of decimals we remove the decimal point and reduce the ratio to a ratio of whole numbers.', 'We multiply the numerator and denominator of the ratio in fraction form by a 10, 100, 1000 i.e., a power of ten to eliminate the decimal.']

First, guess a convenient value for the square root. Divide the number by your guess. Now you have two numbers that multiply to get your original number. Take the average of these two numbers.

So, to get the decimal, you do 1÷5 . This makes you get 0.2 .

Adding and Subtracting Decimals To add decimals, follow these steps: Write down the numbers, one under the other, with the decimal points lined up. Put in zeros so the numbers have the same length (see below for why that is OK) Then add using column addition, remembering to put the decimal point in the answer.

3. To calculate the average, divide the total by the number of readings. If we look at the example above: The total is 765, divided by 5 = 153, which is average A. The total is 406, divided by 5 = 81, which is average B.

Once you have calculated the decimal values of each percentage for each given sample size, you then add these decimal values together and divide the total number by the total sum of both sample sizes. You then need to multiply this value by 100 to get the average percentage.
