## How to Explore PH Civil Service Exam Reviewer

The PH Civil Service Exam Reviewer website (civilservicereview.com) has already provided free reviewers for the past two years and so far many testimonials have already reached me that this website has been very useful in this review. Below are some of the useful links within the website that are often ignored or missed especially when browsing using mobile phones.

1.) Math – The math page contains basic concepts in numerical ability such as operations on fractions, decimals,  solving equations, as well as finding areas of geometric figures. This also includes topics like LCM, GCF, and addition of positive and negative integers. If you are not very good in math, I suggest that you start with this page.

2.) Word Problems – The Word Problems page contains detailed tutorials about word problems. This includes number problems, age problems, motion problems, work problems, mixture problems, coin problems, investment problems, ratio problems, digit problems, and more.

3.) English – The English page contains reviewers on vocabulary, grammar and correct usage, and paragaraph organization. It also contains basic grammar tutorials particularly the tenses of the verbs.

4.) Practice Tests – This contains practice tests and exercises on both English and Math topics discussed in the site.

5.) Post List – contains the complete of posts of this website. This includes list of Civil Service Exam Passers.

6.) Videos – Useful videos from Sipnayan for learning mathematics.

Another useful site is the Sipnayan Youtube Channel which contains more than 300 Tagalog Math Tutorial videos. 🙂

Lastly, as a bonus, if you already passed the Civil Service Exam, then you may want to explore our partner website, the Philippine Government Jobs, if you want to work for the Philippine Government.

## How to Compare Decimal Numbers

We have already learned how to compare fractions and in this post, we are going to learn how to compare decimals. In comparing decimals it is important to understand place value. In the number 213.489, the following are their place values. For the whole numbers,

2 – hundred
1 – tens
3 – ones.

For the decimal numbers,

4 – tenths
8 – hundredths
9 – thousandths

In whole numbers, clearly, the larger the number of digits the larger the number. For example, 821 > 92 since 821 has three digits and 92 has only two digits. Since whole numbers are always greater than decimal numbers in comparing decimal numbers, look at the whole numbers first. Therefore, we have the following rule.

Rule 1: In comparing decimal numbers, look at the whole number first. The decimal numbers containing larger whole numbers have larger values.

Example 1: 84.23 > 82.345 since 84 is greater than 82.

Example 2: 12.56 < 15.001 since 12 is less than 15.

Example 3: 141.85 > 123.4 because 141 is greater than 123

Rule 2: If the whole numbers are equal, then compare the numbers by looking at the tenths place first. The number with the larger digit in tenths place is larger.

Example 1: 18.34 > 18.21 since 3 > 2.

Example 2: 12.95 > 12.15 since 9 > 1.

Example 3: 0. 9 > 0.873 since 9 > 8.

Notice that in Rule 2 Example 3, even if 0.873 has more digits, it is still less than 0.9 since 9 is greater than 8 and they are in the tenths place.

Rule 3: If the whole numbers and the tenths place are equal, then compare first the hundredths place. The number with the larger digits in the hundredths place is the larger number.

Rules 2 and 3 can be generalized. That means that you have to compare the digits from the tenths place first, then hundredths, then thousandths, and so on.

Please take note however the rules of negative numbers.

• Positive numbers are always greater than negative numbers.
• If both numbers are negative, do the following:

1.) Make them positive
2.) Apply the rules above
