The highest common factor is the greatest number which both numbers can divide by evenly. In this case, the greatest number 40 can divide by is 40. 80 can also divide by 40, and so this is a common factor. As no numbers greater than 40 will be able to divide 40 evenly, the hcf of 40 and 80 is 40.
The average of five numbers whose sum is 200 will always be 40, no matter which numbers you choose. When finding an average, you add up the numbers (find the sum of the set), then divide by the number of terms. In this case, the sum will always be 200, and there will always be five terms. This will always result in an average of 40. Ex/ 1 + 2 + 3 + 4 + 190 = 200 200 / 5 = 40 40 + 40 + 80 + 24 + 16 = 200 200 / 5 = 40
In order to change 3/40 to a decimal, you would have to divide the numbers. 3 divided by 40 = .075
35 as in 30 + 40 = 70 then as there are two numbers divide by two, then 70 / 2 = 35 or 30 + 5 = 35 = 40 - 5
Add the 4 numbers and divide by 4. answer = 100/4 = 25
