8 plus 7 divided by 5 then add 6.
It is: 6 because (6*7)+8 = 50
When you add 8 and 5 the sum will be 13. On the other hand when you add 6 and 7 the sum will be 13. That's why it's equal to 13.
6 - 4 1/8 = 1 7/8

10 and 4, 9 and 5, 8 and 6, 7 and 8,
Oh, what a lovely question! To find the average of those numbers, you simply add them all together and then divide by how many numbers there are. So, for 6, 7, and 8, you would add them (6 + 7 + 8 = 21) and then divide by 3 (since there are 3 numbers), giving you an average of 7.

Halfway between 6 and 8 is the average of the two numbers. To find the average, you add the two numbers together and then divide by 2. In this case, (6 + 8) / 2 = 14 / 2 = 7. Therefore, the number halfway between 6 and 8 is 7.
There are no three consecutive numbers that add up to twenty.Proof:5+6+7=186+7+8=217+8+9 = 24
