Answer:
19
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
[tex]12\frac{2}{3}\div\frac{2}{3}[/tex]First, let's convert the mixed number 12 2/3 into a fraction, so:
[tex]12\frac{2}{3}=\frac{(12\times3)+2}{3}=\frac{38}{3}[/tex]Now, we can make the division of the fractions as
[tex]\frac{38}{3}\div\frac{2}{3}=\frac{38}{3}\times\frac{3}{2}=\frac{38\times3}{3\times2}=\frac{114}{6}=19[/tex]It means that Tyra can make 19 batches of oatmeal cookies.
