Answer 2

Answer:

a) -0.07 and b) -0.92

Step-by-step explanation:

Given numbers are -4/13, 5/13, -7/13, 11/13, -12/13 and 9/13. We can also write them as -0.31, 0.38, -0.54, 0.85, -0.92 and 0.69.

We need to a) find out the sum of the highest number and least number. b) divide the highest number with least number.

From above we can say that value of highest number will be in positive while that of least number will be in negative.

Therefore,

Highest number = 0.85 or 11/13

Least number = -0.92 or -12/13

a) Sum = 0.85 + (-0.92) = 0.85 - 0.92 = -0.07

b) Divide = 0.85/(-0.92) = -0.92
