Math : Conversion of Fraction, Decimals, and Percent – Lesson Series

Fractions to Decimals, Fractions to Percentages, Decimals to Fractions, Decimals to Percentages, Percent to Decimals, and Percent to Fractions – You have to get used to converting one into another if you want to pass the Civil Service Exam.

So to get you started, let me start by saying that Decimals, Fractions and Percentages are just like Number Synonyms. For example, 0.25, 1/4, and 25% – they all tell you the SAME THING. They are simply different ways of showing a part of a ‘whole’. That being said, it is EASY to convert their values if you just remember the right steps. Remember that what we discuss here are quick and easy steps that will help you deal with the CSE Math questions.

Basic points to remember when converting Fractions, Decimals, and Percent:

  • In a fraction, the top number is the Numerator and the bottom number is the Denominator.
  • Be careful when counting the decimal places. Here, decimal place refers to the number of digits to the right of a decimal point. So, in 0.25, 25 has two decimal places; in 0.001, 1 has three decimal places; in 0.058, 58 has three decimal places; and in 0.06, 6 has two decimal places.
  • The number to the left of the decimal point is the integer. The number to the right of the decimal point is the fractional part.
  • ‘Percent’ is a number or ratio expressed as a fraction of 100.

While I was managing a fledgling online business and being a full-time mom to my four kids - Yana, Yshi, Yza and Vincent Jr., I took the Career Service Examination - Pencil and Paper Test - Professional Level (CSE-PPT- Prof) for the first time in December 2015. I passed and I got lucky enough to be among the Top 10 examinees in my batch, 3rd in the National Capital Region.
