Answer 2

Answer:

Option (a) is correct.

The best estimate of the difference for the given numbers is -3.

Step-by-step explanation:

Given : $(\frac{34}{8}- \frac{16}{3} )-\frac{14}{9}$

We have to find the best estimate of the difference for the given numbers.

Consider the given $(\frac{34}{8}- \frac{16}{3} )-\frac{14}{9}$

$\frac{34}{8} \approx \frac{32}{8}=4$

$\frac{16}{3}\approx \frac{15}{3}=5$

and $\frac{14}{9}\approx \frac{18}{9}=2$

So, $(\frac{34}{8}- \frac{16}{3} )-\frac{14}{9}$

estimates to

$=(4-5)-2$

Simplifies to

= -1 - 2    

= -3

Thus, The best estimate of the difference for the given numbers is -3.
