What approximate value should replace the question mark (?) in the given expression?

$319.95÷39.98+195.89÷13.97-9.02=?$

The correct answer is 13.

To find the approximate value of the given expression, we round each decimal number to its nearest integer:

$319.95\approx 320$

$39.98\approx 40$

$195.89\approx 196$

$13.97\approx 14$

$9.02\approx 9$

Now, substitute these approximate values into the given expression:

$?\approx (320÷40)+(196÷14)-9$

Following the BODMAS/PEMDAS rule, perform the division operations first:

$320÷40=8$

$196÷14=14$

Substitute these values back into the expression:

$?\approx 8+14-9$

Now perform addition and subtraction from left to right:

$8+14=22$

$22-9=13$

Hence, the approximate value that should replace the question mark (?) is 13.
