How many 1/3 liters are in 4 2/3 liters

jonny [76]

Answer:

14

Step-by-step explanation:

This is a division problem.

We want to find how many 1/3 liters are in 4⅔ liters.

We divide to obtain:

$\frac{4 \frac{2}{3} }{ \frac{1}{3} }$

Or

$4 \frac{2}{3} \div \frac{1}{3}$

Convert to improper fraction.

$\frac{14}{3} \div \frac{1}{3}$

$\frac{14}{3} \times \frac{3}{1}$

This simplifies to

$14$

Therefore there are fourteen ⅓ liters in 4⅔ liters
