The difference between two whole numbers is 300, and one of the numbers is less than 400. We need to determine which of the given options could be the other number.
To find the possible values, we need to subtract 300 from each of the options and see if the result is less than 400.
Let's check each option:
A. 80 - 300 = -220 (less than 400)
B. 100 - 300 = -200 (less than 400)
C. 180 - 300 = -120 (less than 400)
D. 570 - 300 = 270 (greater than 400)
E. 750 - 300 = 450 (greater than 400)
From the calculations, we can see that options A, B, and C result in numbers that are less than 400 when subtracted by 300. Therefore, the other number could be either 80, 100, or 180.
In summary, the possible numbers that could be the other number in this scenario are:
A. 80
B. 100
C. 180
