Question

I need help with work

Answer 1

First of all, we need to write a relation to get the specific orange, it was made with 2 pints of red and 3 pints of yellow, and in the equation it means:

`1\text{ special orange = 2 pints of red + 3 pints of yellow}`

Now, we have 9 pins of yellow and we want to know how many pins of red we need to produce the same color of special orange.

To solve that you need apply the rule of three, like this:

`\begin{gathered} ;\text{ pints of red--- pints of yellow } \\ \text{ 2-------------- 3} \\ \text{ X-------------- 9} \end{gathered}`

to find the value of x, we multiply in cross 2*9 and divide by 3, like this:

`x=(9\cdot2)/(3)=(18)/(3)=6`

Finally, your answer is: for 9 pints of yellow, you need 6 pints of red color to produce the special orange.
