Ana drinks chocolate milk out of glasses that each hold 1/8 of a leader. she has 7/10 of a liter of chocolate milk in her refrig

PIT_PIT [208]

Amount of chocolate milk Ana drinks = $\frac{1}{8}$ liter

Total amount of chocolate milk in refrigerator = $\frac{7}{10}$ liter

We have to determine the total number of glasses she will pour $\frac{1}{8}$ liter of milk from $\frac{7}{10}$ liter of milk.

Total number of glasses will be determined by dividing the total amount of milk by the amount of milk required for one glass

Total number of glasses = $\frac{7}{10} \div \frac{1}{8}$

= $\frac{7}{10} \times 8$

= $\frac{56}{10}$

= 5.6 glasses

So, 5.6 glasses will be poured from the given amount of chocolate milk.
