To do: Find 24% of 12 L Solution: Your question is to find 24% of 12 Litre. 24% of 12 Litre = $\frac{24}{100}\times12$  =$\frac{24\times12}{100}$  =$\frac{288}{100}$ =$2.88$LTherefore , $24%$ of $12$L is $2.88$L$2.88$LTher\frac{24}{100}\times{12}

We know that, For a regular n-sided polygon:Each interior angle = 180−(360°n\frac{360\degree }{n}n360°​)Given that, Each interior angle measures 165°.Let the number of sides be n.Therefore, 165°=180°−(360°n)360°n=180°−165°360°n=15°n=360°15°n=24 \begin{array}{l}165\degree =180\degree -\left(\frac{360\degree }{n}\right)\\\\\frac{360\degree }{n} =180\degree -165\degree \\\\\frac{360\degree }{n} =15\degree \\\\n=\frac{360\degree }{15\degree }\\\\n=24\end{array}165°=180°−(n360°​)n360°​=180°−165°n360°​=15°n=15°360°​n=24​The number of sides is 24.Read More

A number is a mathematical object used to count, measure, and label.The original examples are the natural numbers 1, 2, 3, 4, and so forth.For being manipulated, individual numbers need to be represented by symbols, called numerals; for example, "5" is a numeral that represents the number five.We use the ...
