Question

15:45 into percentage​ with method please

Answer 1

• As per the data given in the question, we have to determine the required number.

       Given data:- $15:45$ into a percentage.

        Solution:-

• A percentage is a fraction of an amount expressed as a particular number of hundredths of that amount.
• It is denoted by $\% .1 \% means \frac{1}{100}.$
• We are using the unitary method to calculate the percentage of numbers.
• Fractions can be converted into percentages and vice-versa.
• Percentages are reversible. For example, $30 \% of 40$ is the same as$40 \% of 30.$

       Therefore,

      $=\frac{15}{45}\times100\\=\frac{100}{3}\\=33\frac{1}{3}\%.$

  Hence, the value will be $33\frac{1}{3}\%.$

Answer 2

To convert : given ratio  into percentage

given : $15 : 45$

• As we know percentage is the fraction amount which can be  expressed as a number of hundredths of that amount.  

• Percentages are reversible.
• as we know $15 : 45$ can be written as  $\frac{15}{45}$
• hence to find percentage  we have to divide numerator by denominator and the multiply the answer by $100$

             ⇒     $\frac{15}{45} \times 100$

                 $= 0.33 \times 100$

                 $= 33\ \%$

Hence, the answer will be $33\ \%$
