How many quarter pound buyers can george make out of 3 and 1/2 pounds of ground beef?

Divide the total amount by the portion size.

= 3 1/2 ÷ 1/4
convert 3 1/2 to improper fraction

= (2*3+1)/2 ÷ 1/4
= 7/2 ÷ 1/4

to divide a fraction, we multiply by the reciprocal/inverse of 1/4

= 7/2 * 4/1
multiply numerators, then multiply denominators

= (7*4)/(2*1)
= 28/2

= 14

ANSWER: 14

Hope this helps! :)
