PCSR REVIEW SERIES WEEK 2: Addition and Subtraction of Fractions

PCSR REVIEW SERIES for October 2016
Week 2: Addition and Subtraction of Fractions

In Week 1 of our PCSR Review Series , we have learned how to get the Least Common Multiple (LCM) and Greatest Common Divisor (GCD) of two or more numbers. The LCM is used to add and subtract dissimilar fractions. To add or subtract fractions, you have to get the LCM of their denominator and convert them to similar fractions.

The GCD is used for converting fractions to lowest terms. In converting fractions to lowest terms, you have to get the GCD of the numerator and denominator of a fraction, and divide both the numerator and the denominator by the GCD.

There are two more skills you need to know: to convert improper fractions to mixed fractions. Most of the time, final answers are required to be in mixed fractions. Links to tutorials on how to do it are included below.

Practice Exercises
I. Find the GCD of each of the following.
a.) 6, 10
Answer: 2

b.) 18, 42
Answer: 6

c.) 12, 48, 60
Answer: 12

d.) 56, 72
Answer: 8

e.) 225, 75
Answer: 75

II. Find the LCM of each of the following.
a.) 3, 4
Answer: 12

b.) 2, 5
Answer: 10

c.) 3, 6, 8
Answer: 24
d.) 3, 4, 5
Answer: 60

e.) 6, 12, 15
Answer: 60

III. Practice Problems Solutions and Answers

1.) 24 (GCD of 3, 4, and 8)

2.) 15 (GCD of 3 and 15)

3.) Solution: GCD of 3, 7, and 21 is 42. They will be seen in the gym on the same day in 42 days. Since June has 30 days, we need an additional 12 days to complete the 42 days. Therefore, they will be seen on the same day on July 12 (of the same year of course).

Answer: July 12

4.) Solution: The LCM of the two sequences is 12 and since we are looking for the tenth common number, we multiply 12 by 10. This gives us 120.
Answer: 120

5.) (a) Solution: LCM of 24 and 30 is 6. That is 6 groups.
(b) Solution: From (a) we can form 6 groups. There are 30 + 24 = 54 students. So in each group, there are 54/6 = 9 members. Since there are 6 groups, we divide each Grade level by 6. That is, 24/6 = 6 Grade 11 and 30/6 = 5 Grade 12 students in each group.
Answer: 4 Grade 11 students and 5 Grade 12 students.

6.) Reduce 42/56 to lowest terms.
Solution: GCD of 42 and 56 is 14. 42 divided by 14 is 3 and 56 divided by 14 is 4. Therefore, the lowest terms is 3/4.
Answer: 3/4

7.) Answer: 24 (LCM of 6 and 8)

8.) Answer: 6 (GCD of 18 and 12)

9.) Solution: The GCD of 21, 35, and 84 is 7. So, the cube has a side length of 7 cm.
Answer: 7 by 7 by 7

10.) Answer: 30 (GCD of 3, 5, and 6).

Inspiring Comments From You – Thank You!

I have collected several comments from this blog at nakakatuwa at nakakataba ng puso na naappreciate nyo ang civilservicerview.com. These comments inspire me to write more.

Marami pa akong nakalinyang topics na isusulat. Kahit pasado na kayo sa Civil Service Exam, I am encouraging you to read them. Puntahan nyo rin ang Sipnayan.com, maraming tagalog math videos doon kung gusto nyo mag-aral ng math.

Ang pagaaral, lifetime yan. Hindi yan nagtatapos pag-graduate ng college. Pag marami kayong alam, marami kayong matutulungan (believe me, knowledge is really power). Kung single kayo, magagamit nyo yan later sa mga anak ninyo or kung kailangan nyo ng part-time job, pwede kayo magtutor kung alam nyo ang Math at English. Pag bihasa kayo sa Math and English, any exam na i-take ninyo in the future, hindi kayo masyadong mahihirapan.  » Read more

What is the Philippine Civil Service Examination?

The Philippine Civil Service Examination is given by the Civil Service Commission (CSC) to aspirants who want to work in the Philippine government. All government employees aside from a few exceptions (like passing selected board exams) are required to take the CSC Examination to be granted tenure.

There are two levels of Civil Service Examinations: Subprofessional and Professional. The Subprofessional level is for those who have finished 2-year courses or below. Those who have graduated 4-year courses or beyond are advised to take the Professional level.

The CSC examination is mainly composed of English and Mathematics proficiency. The other areas include Filipino, office filing and ethics, and Philippine constitution particularly Republic Act 6713.  As of this writing, the passing score of the CSC Examination is 80%.

This blog will serve as a Civil Service Reviewer for those who want to take the examination. I will be discussing questions that are similar to the examination and provide answers, detailed explanations, and tips. I will also give online mock exercises and examinations. In addition, I will also provide updates, links, and examination results.

For now, I will be discussing Mathematics and English subjects. The other subjects such as Philippine constitution will be discussed later by more qualified persons.
