Final answer:
The exact difference of the expression is 13/12. The estimated difference is approximately 1.08.
Step-by-step explanation:
To find the exact difference of the expression 9(5)/(12) - 8(1)/(3), we need to perform the calculations. First, simplify the fractions: 9(5)/(12) = 45/12 and 8(1)/(3) = 8/3. Then, subtract the second fraction from the first: (45/12) - (8/3) = (45/12) - (32/12) = 13/12. Therefore, the exact difference is 13/12.
To find the estimated difference, we can use rounded values for the fractions. 45/12 is approximately 3.75 and 8/3 is approximately 2.67. Subtracting these rounded values, we get an estimated difference of approximately 1.08.
