Lesson 1: Fractions Lesson 3: Ratio & Rate
Fractions - represents a part of a whole Ratio- Comparison of two quantities by
Simplify: division.
The ratio can be written in two different
Word Problem: ways :
Odds notation - a:b ( “:” read as “is to”)
Fractional notation : a/b
Rate- Ratio that compares quantities of
different units. A unit rate is a rate that
has a denominator of 1; that is, a rate
for one unit of a given quantity.
Word Problem
In a class of 40 students, the ratio of
passing grades to failing grades in 5:3.
How many failed the course?
5:3 = PASS:FAIL
5 + 3 = 8 (Totality of all student who
passed and failed)
Lesson 2: Decimals & Percent 40(Total number of students) / 8 = 5
decimal - a representation of a fraction 5 (5): 3 (5)
whose denominator is a multiple of 10
5 x 5= 25 Passed
Word Problem 5 x 3 = 15 Failed
25 (Passed): 15 (Failed) = 40 students

PHP2.30. If Maria is given PHP700, will 5:2:7. If the total number of chocolates
she be able to buy everything she was from the bags containing the least and
asked to buy? If yes, how much change the most number of chocolates is 252,
is left (If there is any)? how many chocolates are there in all?
Sol.
Answer: Yes. 2 (the least) +7(the most) = 9
Pork: 2 ½ x 215 = P537.5 = 28
Garlic: ¼ x 105 = 26.25 5(28) + 252
Saba: 2.3 x 6 =13.8 = 392
Total: 537.5 + 26.25 + 13.8 = 577.55

Word Problem Yvette’s Flower Shop imposes a 45%
A stuffed toy costs ₱260 to mark-up on flowers delivered to them
manufacture and is marked up 45% for sale. During All Saint’s Day,
based on cost. What is the retail however, an additional mark-on of 25%
price of the stuffed toy? of the regular selling price is added on.
