Question

I want to know how fluid ounces of tomato paste I need.

Answer 1

The problem says that the ratio of fluid ounces of water to fluid ounces of tomato paste is 3:4, which means for every 3 ounces of water you add 4 more ounces of tomato paste, then the sauce is compounded by a total of 3+4=7 fluid ounces of both ingredients.

Then, the proportion is:

`\frac{4\text{ fluid ounces of tomato paste}}{\text{7 fluid ounces of sauce}}`

Then, to find how many fluid ounces of tomato paste do you need to make 35 fluid ounces of sauce you can solve the next equation:

`\begin{gathered} (4)/(7)=(x)/(35) \\ \text{ Multiply both sides by 35} \\ (4\cdot35)/(7)=(x\cdot35)/(35) \\ \text{Simplify} \\ 4\cdot5=x \\ x=20 \end{gathered}`

Then, the answer is you need 20 fluid ounces of tomato paste to make 35 fluid ounces of sauce.
