Q: What number is halfway between 100 and 400?

Write your answer...

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.

375

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

550

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.

375

It is 350

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.

It is (350 + 450)/2 = 400

The answer is 400-100-1 = 299 (excluding both 100 and 400).

It is 450

How many even number between 100 to 400? Many says that the answer is 200. That's Wrong Because, in the problem there is a word "Between" Solution: Count how many even number from 1 to 100 and multipliy it by 4. and we have 50 * 4 = 200 - 2 = 198

13% of 400 = 400*13/100 = 52

40% of 400 = 400*40/100 = 160

135% (of a certain number) = 540, therefore 100% (of a certain number) = 100 x 540/135 = 400 The missing number is 400.

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

400

It is: CD which means -100+500 = 400

500

50, 20, 25, 10, 5, and 12.5 don't divide into 4 but all of them divide into 400. There is no number that I can think of that is not a factor of 400 but is a factor of 100 as 100 is a factor of 400, so whatever number makes up 100 must make up 400.

LCM is 400LCM means the lowest number that is divisible by both of the numbers (excluding zero).400/400 = 1400/100 = 4

100 is the greatest common factor between 300 and 400
