Let's solve each part of the problem step-by-step:
4675 - 575
To find this difference, we subtract 575 from 4675: 4675 − 575 = 4100 Therefore, the correct answer is ii. 4100 .
Difference of the largest 3-digit number and the smallest 3-digit number
The largest 3-digit number is 999, and the smallest is 100. Their difference is calculated as follows: 999 − 100 = 899 Therefore, the correct answer is i. 899 .
3796 - 100
Subtracting 100 from 3796 gives: 3796 − 100 = 3696 However, this part of the exercise is asking for an option which seems to be a typographical error, but based on the available options the closest is 3796 with subtraction done.
55 + 55 = 100 + _
We need to solve for the missing part when equating two expressions: 55 + 55 = 110 Hence: [100 + x = 110 \
x = 110 - 100 = 10] Therefore, the correct answer is i. 10 .
45 - 45 = 30 + _
We need to solve for the missing part when equating two expressions: 45 − 45 = 0 Hence: [30 + x = 0 \
x = 0 - 30 = -30] However, there seems to be no correct option provided, indicating a possible typographical error but based on calculations, -30 satisfies the requirements.
These calculations are focused on basic subtraction and understanding of arithmetic relations within given equations, central to mastering middle school algebra.
