Answer:

19

Step-by-step explanation:

To know how many batches of oatmeal cookies she can make, we need to divide 12 2/3 by 2/3. So, we need to solve the following expression


12(2)/(3)/(2)/(3)

First, let's convert the mixed number 12 2/3 into a fraction, so:


12(2)/(3)=((12*3)+2)/(3)=(38)/(3)

Now, we can make the division of the fractions as


(38)/(3)/(2)/(3)=(38)/(3)*(3)/(2)=(38*3)/(3*2)=(114)/(6)=19

It means that Tyra can make 19 batches of oatmeal cookies.
