There are two ways to solve this:
Find the difference by subtracting the smaller number from the larger.
3600 - 400 = 3200
Divide the difference by two.
3200 / 2 = 1600
Add that quotient to the smaller number.
400 + 1600 = 2000
Secondly, the mid point is also the average (for most cases)
400+ 3600 = 4000
4000 / 2 = 2000
550
350 It is 50 more than 300 and 50 less than 400 To find a halfway point (which is also the average), add the numbers together and divide by 2.
The Highest Common Factor is 40
There are 151 even numbers between 100 and 400. To find this, you can use the formula for calculating the number of integers in a range: (largest number - smallest number) / 2 + 1. In this case, it would be (400 - 100) / 2 + 1 = 151.
How about 450
You see that there is a difference of 400 between the two numbers. Therefore, just take 400 divided by 2. This equals 200 and if you add 200 to 3600, it adds up to 3800.Another way to do this is simply find the average of the two numbers. Add 3600 and 4000 which equals 7600. Now Take 7600 divided by 2. This makes the averege of the two numbers which is 3800.
550
440 as it is the number that is halfway between them, or half of their total.
400
500
400 / 3600 = ~ 11.11% (.11 repeats)
The LCM is 3600.
400 400 is 100 more than 300 and 100 less than 500. To find the halfway point (the average), add the two numbers and divide by 2.
350 It is 50 more than 300 and 50 less than 400 To find a halfway point (which is also the average), add the numbers together and divide by 2.
It is 350
It is (350 + 450)/2 = 400
It is 450
