svp [43]

Answer: There are 13 slices when Dario cuts .

Explanation :

Since we have given that

Quantity of parmesan cheese is given by

\frac{2}{3}

Quantity of ricotta cheese is given by

1\frac{1}{4}

Quantity of mozzarella cheese is given by

1\frac{1}{3}

Now, total  quantity of cheese Dario have

\frac{2}{3}+\frac{5}{4}+\frac{4}{3}=2+\frac{5}{4}=\frac{8+5}{4}=\frac{13}{4}

Now,

According to question, Dario cuts the lasagna into several equal slices and each containing exactly

\frac{1}{4}\ pounds\ of\ cheese

So,

Number of slices is given by

\frac{\frac{13}{4}}{\frac{1}{4}}=13

Hence, there are 13 slices when Dario cuts .
