Your answer would be: 20/3 = 6 2/3. Hope I helped!

Answer: Required expression is,

[tex]\frac{2\times 1\frac{1}{4}+\frac{5}{2}}{\frac{3}{4}}[/tex]

Approximately 7 cans are required.

Step-by-step explanation:

Given,

The number of cups required for lasagna recipe = [tex]1\frac{1}{4}[/tex]

After doubling lasagna recipe, the number of cups required = [tex]2\times 1\frac{1}{4}[/tex]

Also, the number of cups required for each pizza = [tex]\frac{1}{2}[/tex]

If the number of pizza = 5,

Then the number of cups required for 5 pizza = [tex]\frac{5}{2}[/tex]

So, the total cups required = [tex]2\times 1\frac{1}{4}+\frac{5}{2}[/tex]

Hence, number of '3/4-cup cans' of tomato paste

[tex]=\frac{\text{Total cups required}}{\frac{3}{4}}[/tex]

[tex]=\frac{2\times 1\frac{1}{4}+\frac{5}{2}}{\frac{3}{4}}[/tex]

[tex]=\frac{2\times \frac{5}{4}+\frac{5}{2}}{\frac{3}{4}}[/tex]

[tex]=\frac{\frac{10}{4}+\fra{5}{2}}{\frac{3}{4}}[/tex]

[tex]=\frac{\frac{10+10}{4}}{\frac{3}{4}}[/tex]

[tex]=\frac{\frac{20}{4}}{\frac{3}{4}}[/tex]

[tex]=\frac{20}{3}[/tex]

[tex]=6.667\approx 7[/tex]
