I. Look at the equation \( 628-275= \) ?. Which equation is related? Choose the correct equation. \( \begin{array}{ll}\text { A. } 628+275=\text { ? } & \text { B. } 275+?=628 \\ \text { C. } ?-275=628 & \text { D. } 275+628=\text { ? }\end{array} \)

To determine which equation is related to \( 628 - 275 = ? \), let's analyze each option: 1. **Original Equation:** \[ 628 - 275 = ? \] Here, we are solving for \( ? \). 2. **Option A:** \[ 628 + 275 = ? \] This involves addition instead of subtraction, which is not directly related to the original equation. 3. **Option B:** \[ 275 + ? = 628 \] This can be rearranged to solve for \( ? \): \[ ? = 628 - 275 \] This is exactly the original equation, just rearranged. Therefore, this option is directly related. 4. **Option C:** \[ ? - 275 = 628 \] Solving for \( ? \) gives: \[ ? = 628 + 275 \] This results in a different value than the original equation. 5. **Option D:** \[ 275 + 628 = ? \] Similar to Option A, this involves addition and is not directly related to the original subtraction equation. **Conclusion:** The equation that is directly related to \( 628 - 275 = ? \) is: **B. \(275 + ? = 628\)**
