The document provides examples of solving for missing terms in proportions. It explains the two step process of: 1) dividing the smaller number by the bigger number, and 2) multiplying the answer diagonally by the remaining number. Several practice problems are included for finding missing terms in proportions.

1. Finding the
missing term
in a proportion.

3. GIVE THE EQUIVALENT RATIOS OF THE FOLLOWING.
4 : 8
1)
2) 12 : 12
3) 2 : 4
4) 5 : 25

4. CLAP ONCE IF RATIOS ARE EQUIVALENT
CLAP TWICE IF NOT.

5. 4 : 8 1 : 2

6. 3 : 8 1 : 4

7. 6 : 8 3 : 4

8. 3 : 5 5 : 15

9. 7 : 14 1 : 2

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
9
2
5

3

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 400km?

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
