Step 1: Adding The Numbers Together
The first step in calculating the mean is to add the two numbers together. In this case, we need to add 3/4 and 5.
To add these two numbers together, we need to find a common denominator. The common denominator for 3/4 and 5 is 4. We can rewrite 5 as 20/4, which makes it easier to add the two numbers together.
3/4 + 20/4 = 23/4
Converting the Fraction to a Decimal
To make the calculation process easier, we can convert the fraction to a decimal. To convert 23/4 to a decimal, we can divide the numerator by the denominator.
23 ÷ 4 = 5.75
Step 2: Dividing By The Total Number Of Values
Now that we have the sum of the two numbers, we need to divide by the total number of values. In this case, the total number of values is 2.
To calculate the mean, we can divide 5.75 by 2.
5.75 ÷ 2 = 2.875
The Answer Revealed
So, what number do we divide by to calculate the mean of 3/4 and 5? The answer is 2.
By dividing the sum of the two numbers by 2, we can calculate the mean of 3/4 and 5. In this case, the mean is 2.875.
