Convert numbers to decimal
Simply, divide the first number (the result of percentage) by the second number (total number, that means it is 100%) example: 5 is what percent of 50 the decimal number is 5 / 50 = 0.1
Multiply the decimal number by 100 to get the percentage
like in the example above, we have 0.1 the decimal number so the percentages = 0.1 x 100 = 10%
