The total of 45 + 55 + 5 = 105
55 - 1, 5, 11, 55 115 - 1, 5, 23, 115 the HCF is 5
23 ______ | | 23 | | 23 |_____| 23 Add up the sides: 23 + 23 + 23 + 23 = 92 92 cm squared

Mean is a fancy word for "Average". To calculate an average of a set of numbers you must add together the set of numbers and divide by the amount of numbers in the set. Let's solve your problem.4, 12, 23, 11, 5. Remember the first step is to add all the numbers together.4 + 12 + 23 + 11 + 5 = 55.Now we need to do step two - which is to divide by the amount of numbers in the set. In this case we added together 5 numbers.55/5 = 11.So the Average of {4,12,23,11,5} = 11.
55
23 plus 4/5 = 23.8
55 + 23 = 78
78-55 = 23
