Answer: The explanation is given below.
Step-by-step explanation: Given that half of an orange juice mixture is orange concentrate.
We are to explain the reason behind the ratio of orange concentrate to water being 1 : 1.
Let x be the quantity of the total orange juice mixture.
Then, according to the given information, the orange concentrate in the mixture will be
[tex]q_o=\dfrac{1}{2}\times x=\dfrac{x}{2}.[/tex]
The rest of the mixture will be water, of course. The quantity of water in the mixture will be
[tex]q_w=x-\dfrac{x}{2}=\dfrac{x}{2}.[/tex]
Therefore, the ratio of orange concentrate to water is given by
[tex]r=q_o:q_w=\dfrac{x}{2}:\dfrac{x}{2}=\dfrac{\frac{x}{2}}{\frac{x}{2}}=\dfrac{1}{1}=1:1.[/tex]
Thus, the ratio of orange concentrate to water is 1 : 1.
Hence explained.
