Question

What approximate value should come in place of the question mark (?) in the following equation?

$99.01 \div 10.93 + 6.987 \times 16.01 = ?$

• A. 133
• B. 145
• C. 121
• D. 129

Answer 1

Answer:

C. 121

The approximate value that should come in place of the question mark is 121.

1. Approximate each decimal to the nearest whole number:

* $99.01 \approx 99$

* $10.93 \approx 11$

* $6.987 \approx 7$

* $16.01 \approx 16$

2. Substitute the values into the equation:

$99 \div 11 + 7 \times 16 = ?$

3. Apply the BODMAS rule (Division and Multiplication first):

* Division: $99 \div 11 = 9$

* Multiplication: $7 \times 16 = 112$

4. Perform Addition:

$9 + 112 = \mathbf{121}$
