Amarket sold two packages of sliced beef weighing 1 and one seventh and 4 and one half lb. what was the total weight of the beef?

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.
