Answer:
The total weight of the beef sold was 6 11/14 lb.
Step-by-step explanation:
Rewriting this info in a symbolic equation, we get:
2(1 1/7 lb) + 4 1/2 lb.
Perform the multiplication first: 2 2/7 + 4 1/2 (lb)
Here the LCD is 14; 2 2/7 = 16/7; and 4 1/2 = 9/2.
We need to combine 16/7 and 9/2. Rewriting them using the LCD, we get:
32/14+63/14 = 95/14. Rewriting this 95/14 as a mixed number, we get:
6.7857 lb (to four decimal places), or 6 11/14 lb.
The total weight of the beef sold was 6 11/14 lb.
