Understanding the Problem
To solve the equation 9654 ÷ 21 + 7638 ÷ 44, we need to find an approximate value for each division before summing them up.
Step 1: Calculating 9654 ÷ 21
- To simplify, we can round 9654 to 9600 for easier calculation.
- 21 is close to 20, so we can use that for estimation.
- The calculation becomes approximately:
9600 ÷ 20 = 480.
Step 2: Calculating 7638 ÷ 44
- Here, we can round 7638 to 7600.
- 44 can be rounded to 40 for estimation.
- The calculation becomes approximately:
7600 ÷ 40 = 190.
Step 3: Adding the Results
- Now, we add the two approximate results together:
480 + 190 = 670.
Refining the Estimation
- The approximate values calculated can be slightly off due to rounding.
- We need a closer approximation to the original numbers.
- Rounding the division steps gives us a better range.
Final Approximation
- Let's reevaluate the direct calculations:
- 9654 ÷ 21 is approximately 460 (instead of 480).
- 7638 ÷ 44 is approximately 170 (instead of 190).
- Now adding these refined estimates:
460 + 170 = 630.
Conclusion
- The closest answer from the options provided is approximately 633.
- Therefore, the correct choice is option 'A' (633).
