The document discusses finding the missing term in a proportion, outlining the process using simple steps: dividing the smaller number across the bigger number and multiplying diagonally with the remaining number. It includes various examples and word problems related to proportions, such as calculating necessary water for buko juice and savings rate scenarios. The instructions are aimed at helping students learn the concept of equivalent ratios and apply it to solve for missing values.

water. How many litres of water does she need
for 3 bukos so that the taste will be the
same.

14. To illustrate the problem.

15. What Is Ask in the problem?
What are given?
Liters of water in 3 bukos
1 buko, 4 liters, 3 bukos
What do we find in this problem?
Liters of water in 3 bukos
To find the no. of liters in 3 bukos let us watch
a video clip.
What will you do while watching?

17. What is the easy way in finding the
missing portion of a proportion? Z way
What is the step 1 in doing this?
Always divine smaller number across the
bigger number.
What next step?
Multiply the answer diagonally with the remaining
number .

18. Using these two steps can we help Zeny in her problem?
÷
x

19. Solve for the missing term.
GROUP 1 - What number compared to 10 is the same as
28 compared to 5?
GROUP 2 - Lisa saves 60 in 4 weeks. At this rate, how long
will it take her to save 300.00?
GROUP 3 - ) Six compared to 11 is the same as 84
compared to what number?

20. What is the easy way in Finding the missing term
of a proportion? Z way
What are the two steps?
The two steps are:
1. Always divine smaller number across the
bigger number.
2.Multiply the answer diagonally with the remaining
number .

21. Solve for the missing term in each proportion.
a) 6:n = 8:12
b) m:7 = 6:21
c) 20:24 = x:6
d) y:6 = 28:84
e) 14:21 = 2:n

22. Find the missing term to make the
proportion true.
a) 9:N = 27:15
b) N:8 = 12:32
c) 5:3 = 25:N
d) A motorist traveled 240 km in 3 hours. At the same
rate, how long will it take to travel 400
km?

23. Find the missing term in proportion.
a) 2/4 = 28/n
b) 18:45 = n:9
c) n/48 = l5/36
d) n:21 = 6:30
e) 9:12 = 27:n
