Answer:

The best estimate is -95/36

Explanation:

Given expression =
((34)/(8) -(16)/(3) ) -(14)/(9)


=((34)/(8) -(16)/(3) ) -(14)/(9)\\\\ = ((17)/(4) -(16)/(3) ) -(14)/(9)\\\\= ((3(17) - 4(16))/(12) ) -(14)/(9)\\\\=((51- 64))/(12) ) -(14)/(9)\\\\= ((-13)/(12) ) -(14)/(9)\\\\= (-117 - 168)/(108) \\\\= (-285)/(108) \\\\= (-95)/(36)

Thus, the best estimate is -95/36
