Solution :To determine whether they are proportion or not, use cross multiplication
6 : 7 = 12 : 14
6 × 14 = 7 × 12
84=84
Using the cross multiplication, we find out that they have the same product meaning they are proportion

Solution :To determine whether they are proportion or not, use cross multiplication
7 : 40 = 0.5 : 3
7 × 3 = 40 × 0.5
21 = 20
21 ≠ 20
Using the cross multiplication, we find out that they didn't have the same product meaning they are not a proportion

Directions B : Solve the following to find the missing terms
1)A. 40books
10 : 5 as n : 20
10 × 20 ÷ 5 × n
200 ÷ 5n
n = 200 ÷ 5
n =40

2)C. 20men
8 : 15 as n : 6
8 × 15 ÷ n × 6
120 ÷ 6n
n =120 ÷ 6
n =20

3)B. 10days
5 : 8 as 4 : n
5 × 8 ÷ 4 × n
40 ÷ 4n
n = 40 ÷ 4
n =10

4)C. 40
5.C. 16
Solution of 4 and 5 :
5 : 2 in 56
5 + 2 ÷ 56
7÷ 56
8
Multiply 8 to 5 : 2 to come up with the correct answers :
8 × 5 = 40
8 × 2 = 16
So, the ratio 5 : 2 is proportional to 40:16meaning, there are 40coconut trees and 16mango trees

6)C. 40:60:80
Solution : Just like we've done before, add the ratios and divide it to the total then proceed to multiplication
2 : 3 : 4 ÷ 180
2 + 3 + 4 ÷ 180
9÷ 180
20
Next, multiply 20 to the ratio :
2 : 3 : 4 × 20
2 × 20 = 40
3 × 20 = 60
4 × 20 = 80
So, the ratio 2 : 3 : 4 is proportional to 40:60:80 meaning, the three girls sold 40,60and 80a total of 180faceshields
