Answer: The required expression:-(3\times\frac{7}{4}+6\times\frac{2}{3})\div\frac{3}{4}\\
The number of 3/4 cup cans of tomato paste she will need in all. [tex]\frac{37}{4}\ of\ \frac{3}{4}cups[/tex]
Step-by-step explanation:
Given: Required amount of tomato paste for spaghetti sauce= [tex]1\frac{3}{4}\ cups=\frac{7}{4}\ cups[/tex]
Therefore, triple the amount of tomato paste for spaghetti sauce[tex]=3\times\frac{7}{4}[/tex] cans
Required amount of tomato paste for a pizza=[tex]\frac{2}{3}\ cup[/tex]
Therefore, amount of tomato paste for 6 pizzas[tex]=6\times\frac{2}{3}\ cups[/tex]
Total number of 3/4 cup cans of tomato paste she will need in all
[tex]=(3\times\frac{7}{4}+6\times\frac{2}{3})\div\frac{3}{4}\\=(\frac{21}{4}+4)\times\frac{4}{3}\\=(\frac{37}{4})\times\frac{4}{3}=\frac{37}{3}\ (\frac{3}{4}\ cups)[/tex]
