Respuesta :
find total amount
2 lasagnas
2 imes 1 and 1/4=2(1+1/4)=2+2/4=2 and 1/2 cups for lasagna
5 pizzas
5 times 1/2=5/2=4/2+1/2 cups=2+1/2 cups
so total is
lasagna+pizzas=2 and 1/2+2 and 1/2=4+2/2=5 cups
she has 3/4 cup cans
so
3/4 times number of cans=5
times both sides by 4/3
number of cans=20/3
number of cans=18/3+2/3
number of cans=6+2/3
you can't buy 2/3 can so round up
she needs 7 cans

Answer:
The answer is [tex]6\frac{2}{3}[/tex].
Step-by-step explanation:
Given that her lasagna recipe calls for [tex]1\frac{1}{4} =\frac{5}{4}[/tex] cups of tomato paste.
Also, given that she will double her lasagna recipe, then the number of cups of tomato paste will be = [tex]2\times\frac{5}{4} =\frac{5}{2}[/tex]
The pizza recipe uses [tex]\frac{1}{2}[/tex] cup of tomato paste per pizza.
As Jada will make 5 pizzas so, total cups of tomato paste needed will be =
[tex]5(\frac{1}{2} )[/tex] = [tex]\frac{5}{2}[/tex]
Now, the total number of cups of tomato paste used for making double lasagna and 5 pizzas is given by [tex]\frac{5}{2} +\frac{5}{2}[/tex] = 5 cups
Hence, the number of [tex]\frac{3}{4}[/tex] cup cans of tomato paste she will need in all is given by:
[tex]\frac{5}{\frac{3}{4}}[/tex] = [tex]\frac{20}{3}[/tex] = [tex]6\frac{2}{3}[/tex]
