Ratio

A ratio indicates the relative sizes of two quantities. It is a comparison that tells how many times one number contains another. You can express the ratio in three ways. It can be in a word form (m is to p), fraction form (m/p) and colon form (m:p). Just like a fraction, you can also simplify the ratio. To give the simplest form of the ratio, look for the greatest common factor of the numbers and divide them by it.

Let us now answer the exercises above.

Exercise I:

1. 3 shelves for 120 books

Word Form: 1 is to 40

Fraction Form: ‌1⁄40‌

Colon Form: 1:40

2. 12 baskets for 8 shots

GCF = 4

12 ÷ 4 = 3

8 ÷ 4 = 2

Word Form: 3 is to 2

Fraction Form: ‌3⁄2

Colon Form: 3:2

3. 7 stars to a moon

Word Form: 7 is to 1

Fraction Form: ‌7⁄1

Colon Form: 7:1

4. 24 flowers to 5 vases

Word Form: 24 is to 5

Fraction Form: ‌24⁄5

Colon Form: 24:5

5. 50 meters to 85 meters

GCF = 5

50 ÷ 5 = 10

85 ÷ 5 = 17

Word Form: 10 is to 17

Fraction Form: ‌10⁄17

Colon Form: 10:17

Exercise II:

1. The ratio of girls to the number of pupils in the library

Fraction Form: ‌16⁄40 or ‌2⁄5

GCF = 8

16 ÷ 8 = 2

40 ÷ 8 = 5

2. The ratio of the number of parents to the number of teachers

Word Form: 180 is to 30 or 6 is to 1

GCF = 30

180 ÷ 30 = 6

30 ÷ 30 = 1

3. 8 persons to 40 cans of sardines

Fraction Form: 8⁄40 or ‌1⁄5

GCF = 8

8 ÷ 8 = 1

40 ÷ 8 = 5

4. The ratio of pool's length to its shadow

Colon Form: 20:5 or 4:1

GCF = 5

20 ÷ 5 = 4

5 ÷ 5 = 1
