Lucy brought 2 3/4 batches of cookies to share
with her coworkers. By the end of the day 5/6
had been eaten. How many of the cookies
are left?

Respuesta :

Answer:

23/12 (1 11/12)

Step-by-step explanation:

2 3/4 = 11/4 and in order to do 11/4 minus 5/6, you would have to find the LCM (Least Common Multiple). The LCM is 12. 11/4 times 3 is 33/12 and 5/6 times 2 is 10/12. 33/12 minus 10/12 is 23/12. In a mixed fraction, this would be 1 11/12.
