In this question, we have to find

**what it means**by $1 $ ratio $ 1$, also written as $1:1$.The**basic concept**behind this questionnaire is the knowledge and definition of**ratios**in mathematics.## Expert Answer

Generically, a**ratio**is the comparison of**two quantities**that have the**same unit**and can be expressed with the help of $2 $ variables. Let us suppose that $x $ and $y $ are those**two variables**and they should be an**integer**then we can write them in**fraction form**as follows:\[ Ratio = \dfrac{x}{y} \]where$variable \space x\ =\ first \space quantity$$variable \space y\ =\ second\space quantity$By definition**$1:1$ ratio**is actually**one of the portion**or quantity of the whole substance. For more clear understanding let us take an**example**of $10$ liters of**orange juice**in**two containers**.Then we can write it as follows:\[Ratio \space of \space Orange \space juices = \dfrac{10}{10}\]\[Ratio \space of \space Orange \space juices= \dfrac { 1 } { 1 }\]which will be equal or can be written as:\[Ratio \space of \space Orange \space juice = 1:1\]Or let us suppose that we have**spice jars**in our kitchen and in the set we have $ 100$ grams of**salt**and $100 $ grams of**pepper**. Thus, we can write that the**spices salt,**and**pepper**are in a $ 1 :1 $. We can**mathematically express**these quantities as written below:\[Quantity \space of \space salt \space in \space jar=100\]\[Quantity \space of \space pepper \space in \space jar=100\]which will be equal or**can be written**as:\[Ratio \space of \space salt \space and \space pepper=\dfrac{100}{100}\]\[Ratio \space of \space salt \space and \space pepper=1:1\]Now for the same example let us suppose that we have**different quantities**of**spices in jars**and in the given set we have $ 30$ grams of**salt**and $300 $ grams of**pepper**. Thus, we can write that the**spices salt and pepper**are in a $ 1: 10 $. We can**mathematically express**these quantities as written below:\[Quantity \space of \space salt \space in \space jar=30\]\[Quantity \space of \space pepper \space in \space jar=300\]which will be equal or can be written as:\[Ratio \space of \space salt \space and \space pepper=\dfrac{30}{300}\]\[Ratio \space of \space salt \space and \space pepper=1:10\]## Numerical Results

By definition,**$1:1$ ratio**is actually**one of the portions**or quantities of the whole substance when**units are the same**.## Example

$1$ bottle has $6$ liters of**pineapple juice**while the other has $4$ liters of juice.**Calculate the ratio**of these bottles.Given in the question statement, we have:$1$ bottle has $6$ liters of**pineapple juice.****Another bottle**has $4$ liters of pineapple juice.\[Ratio \space of \space pineapple \space juice=\dfrac{6}{4}\]\[Ratio \space of \space pineapple \space juice =\dfrac{3}{2}\]which will be**equal**or can be written as:\[Ratio \space of \space pineapple \space juice = 3: 2\]
