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.
500
300 Find the difference (500-100=400) then halve the sum(200). Add the halved sum to the lowest number in the equaion(100) or subtract the halved sum(200)from the largest number in the equation(500) one:500-100=400 two:400/2=200 Three: 200+100=300 or 500-200=300
It is (350 + 450)/2 = 400
It is 450
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.
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.
500
300 Find the difference (500-100=400) then halve the sum(200). Add the halved sum to the lowest number in the equaion(100) or subtract the halved sum(200)from the largest number in the equation(500) one:500-100=400 two:400/2=200 Three: 200+100=300 or 500-200=300
440 as it is the number that is halfway between them, or half of their total.
It is 350
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.
It is (350 + 450)/2 = 400
It is 450
The statement "300 is between 100 and 400" is equivalent to: 100 < 300 < 400 Or the equivalent: 300 > 100 AND 300 < 400. If you check these statements and see that they are true, then 300 is between the two numbers.
The answer is 400-100-1 = 299 (excluding both 100 and 400).
