What have you seen in the pictures?
Look at the pictures, count the number of girls and boys in their respective rows.
Write your answer on your notebook.

6. Number of Pupils in a Row
Presentation
c. Tabulate the data on your notebook as follows:
d. Ask:
1. How many children in its row?
2. How do you compare the number of boys to the number of girls in Row 1? Row2?
- Compare Row 2 to Row 4?
e. Introduce the concept of ratio.
ROW NUMBER
Row No.
No. of Boys
No. of Girls

7. A ratio is a comparison of two numbers by division.
To write ratios, use the word is to, a colon, or a fraction bar.
EXAMPLE : John read 3 books in 4 days. Write the ratio of books to days.
Words/phrase : 3 is to 4
Colon:
3:4
Fraction:
3/4

8. EXAMPLE #1: Carl and Patrick are twins

Colon:
10: 5
Fraction:
10/5
Words/phrase : 10 is to 5

9. (Group Activity) 3 groups
Performing the Activities
(Group Activity) 3 groups
There are 9 boys and 14 girls in grade six section sampaguita.
Group 1: What is the ratio of girls to boys using a fraction?
Group 2: What is the ratio of girls to children in grade six section sampaguita (use a colon)?
14:23
Group 3: What is the ratio of boys to children in grade six section sampaguita (use words)?
9 to 23

10. Processing the Activities
How did you find the activity?
Did you find the right answer?
How did you express one value as a ratio/fraction and
write them into three different ways/vice versa.
- As a words/ phrase
As colon (:)
As fraction

11. Developing Mastery Collaborative Work
Can you express the following as ratios in three different ways?
Fill in the chart. Expressed the ratios in simplest form.
As a words/phrase
As a fraction
Using a colon(:)
1.) a box of pencil to
₱ 50.00
2.) 5 mangoes to dozen of oranges
3.) 15 minutes to 2 hours
1 is to 50
1 / 50
1:50
5 is to 24
5 / 24
5:24
15 is to 120
15/ 120
15:120

12. Let’s Investigate As a words/phrase As a fraction Using a colon(:)
3.) 15 minutes to 2 hours
15 is to 120
15/ 120
15:120
Try to examine the answer for number 3.
When ratio dealing with measurements, a ratio must be expressed using the same unit of measurements.
Ex. 15 minutes to 2 hours
Since minutes and hours are different unit of measurement we cannot answer immediately by writing as 15 :2, we must convert first the hours into minutes. So, 2 hours = 120 minutes.
That is why, the answer of number 3 became 15:120.

13. Apply your skills
Your father told you to buy 2 kilos of “kuyog”
and 4 kilos of “tarukog.” Now using the three ways
in writing the ratio.
Expressed the ratio of tarukog to kuyog?

14. Generalization
How do we expressed one value as a fraction of another given their ratio and vice versa.
A ratio is a comparison of two quantities.
A ratio can be written in three ways.
- as a words/phrase
- as a fraction
- using a colon

15. A ratio maybe express in simplest form.
Generalization
A ratio maybe express in simplest form.
The order of quantities must be considered in writing a ratio.
When dealing with measurements, a ratio must be expressed using the same unit of measurements.
