The answer is:
Myrna can decorate
dozens of cookies in

Why?To solve this problem, we need to remember how to multiply mixed numbers, we can do it by the following way:
- Covert the mixed numbers to improper fractions
- Multiply the improper fractions
- Convert the result to mixed number again.
Also, we need to pay attetion to the given rate about Myrna's work.
So,
Then, to calculate how many dozen of cookies can Myrna decorate in 2 and 1/3 hours, we need to write the following equation:
We already know the Myrna's rate, so substituting it into the equation to know how many dozen of cookies she can decorate in 2 and 1/3 hours, we have:
Now, multiplying the mixed numbers we have:
- First, converting to improper fractions:
- Second, multiplying the fractions:
- Converting back to mixed number:
So, the answer is:
Myrna can decorate
Have a nice day!
