Question 1009486
To find the average of ANY two numbers, you add them together and then divide by two.
For example, if we wanted the average of 5 and 9, we would add them to get 14 and then divide that by 2, giving an average of 7.
Here, we are given the average and one of the numbers.
Let us call the missing number x.
Then we have
{{{((3/2) + x) / 2 = 7/8}}}
To solve this, and find x, let us multiply both sides by 2 and get
{{{((3/2) + x) = 7/4}}}
Then we subtract 3/2 from both sides and get
x = 7/4 - 3/2 = 7/4 - 6/4 = 1/4
The missing number is 1/4.
