Solving for the Question Mark in the Arithmetic Expression
This problem asks us to find the value that should replace the question mark ('?') in the given mathematical equation. We need to perform the operations inside the parentheses first and then solve for the unknown value.
Step 1: Evaluate the Expression Inside the Parentheses
The expression inside the parentheses is $700 + 800 – 1300 + 800$. Let's calculate this step-by-step:
- First, add 700 and 800: $700 + 800 = 1500$.
- Next, subtract 1300 from the result: $1500 - 1300 = 200$.
- Finally, add 800 to the current result: $200 + 800 = 1000$.
So, the expression simplifies to 1000.
Step 2: Set Up the Simplified Equation
Now, substitute the value we found back into the original equation:
$$1000 \div ? = 200$$
Step 3: Solve for the Question Mark (?)
To find the value of '?', we need to rearrange the equation. We can do this by dividing both sides by 200 or by isolating '?':
$$? = \frac{1000}{200}$$
Performing the division:
$$? = 5$$
Conclusion
The value that should come in place of the question mark is 5. This matches option 1.
