Question

Estimate 5.9 * 3.4
a. about 12
b. about 16
c. about 18
d. about 20

Answer 1

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!

Answer 2

Answer:

C. about 18

Step-by-step 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,

$5.9\times 3.4$

$\approx 6\times 3$

$\approx 18$

Hence, the value of $5.9\times 3.4$ is about 18.

Option C is correct.
