Determine the approximate value that should replace the question mark (?) in the following expression (you are not required to calculate the exact value):
Correct Answer :
5600
Solution :
The correct option is 5600.
To find the approximate value of the given expression, we can round each number to its nearest convenient whole number or simple decimal value to simplify the calculations.
Let us approximate each term in the given mathematical expression:
Now, substitute these approximate values back into the original expression:
Step-by-step simplification:
First, perform the division:
Next, substitute this result back into the expression:
Multiply 20 by 4:
Finally, multiply 80 by 70:
Therefore, the approximate value that should replace the question mark (?) is 5600.
