Answer:

C. about 18

Explanation:

Since, We know that,

5.9 is closer to 6,


5.9 \approx 6,

And, 3.4 is closer to 3,


3.4 \approx 3

Here, the given expression,


5.9* 3.4


\approx 6* 3


\approx 18

Hence, the value of
5.9* 3.4 is about 18.

Option C is correct.

C) about 18
This is because 5.9 is closer to 6 than 5, so 6 *3.4
Next step: 3.4 is closer to 3 than 4 because it is not 3.5 or over.
6 times 3 is 18 so the answer is about 18!
