Question

Tara baked 6 1/2 dozen cookies. She sold 3 2/6 dozen of the cookie she made. How many dozens of cookies does Tara have remaining

Answer 1

Tara baked 78 cookies in total because 6x12+6=78 or 72  6/12 and sold 36  4/12  so she has 24 cookies left hope this helps

Answer 2

One dozen has 12 units.

So 6 and a half dozen shall have 6.5 ×12 = 78 cookies.

She sold

$3\frac{2}{6} =3\frac{1}{3} =\frac{10}{3}$ dozens

So cookies she sold

= $=\frac{10}{3} (12) = \frac{120}{3} =40$

Number of cookies left = 78 - 40 = 38

So 38 cookies

$=\frac{38}{12} =\frac{19}{6} =3\frac{1}{6}$

Tara is left with $3\frac{1}{6}$ dozens
