Answer:
2 1/2
Step-by-step explanation:
Order of operations rules require that we do any work within parentheses first. Thus, calculate (8.75 - 2 5/6); it is (5 11/12). Next, calculate (4 1/2 + 2 2/3); it is ( 7 1/6). So what we have now looks like:
(5 11/12) / 7.1 + (7 1/6) / (43/10) (Note that 4 3/10 = 43/10)
Performing the two indicated divisions, we get:
5/6 + 1 2/3.
Since the LCD here is 6, we add: 5/6 + 1 4/6, which comes out to
1 9/6, or 1 + 1 1/2, or 2 1/2 (answer)
