Answer:
[tex]\frac{13}{30}[/tex] cup of cornmeal.
Step-by-step explanation:
Given:
We have total 5/6 cup of cornmeal.
We have to use 2/5 cup of cornmeal for muffins.
Now, we find left cornmeal by below relation.
Left cornmeal = total cornmeal - used cornmeal
[tex]Left\ cornmeal = \frac{5}{6}-\frac{2}{5}[/tex]
[tex]Left\ cornmeal = \frac{5\times 5-2\times 6}{30}[/tex]
[tex]Left\ cornmeal = \frac{25-12}{30}[/tex]
[tex]Left\ cornmeal = \frac{13}{30}[/tex]
Therefore, the quantity of cornmeal left is [tex]\frac{13}{30}[/tex] cup.
