Respuesta :

The first one is 3:4
Second is 3:1
Third is 2:3
Forth is 1:3
Fifth is 9:7
Last is 6:7

Step-by-step explanation:

We need to write the following ratios with its simplest form.

1. [tex]\dfrac{21}{28}[/tex]    

Factors of 21 = 3, 7

Factors of 28 = 2, 7, 2  

[tex]\dfrac{21}{28}=\dfrac{3}{4}[/tex]  

2. [tex]\dfrac{96}{32}[/tex]    

Factors of 96 =  1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

Factors of 32 =  1, 2, 4, 8, 16, 32

[tex]\dfrac{96}{32}=\dfrac{3}{1}[/tex]

3. [tex]\dfrac{22}{33}[/tex]    

Factors of 22 = 1, 2, 11, 22

Factors of 33 =  1, 3, 11, 33

[tex]\dfrac{22}{33}=\dfrac{2}{3}[/tex]

4. [tex]\dfrac{12}{36}[/tex]    

Factors of 12 = 1, 2, 3, 4, 6, 12

Factors of 36 =  1, 2, 3, 4, 6, 9, 12, 18, 36

[tex]\dfrac{12}{36}=\dfrac{1}{3}[/tex]

5. [tex]\dfrac{72}{56}[/tex]    

Factors of 72 = 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Factors of 56 = 1, 2, 4, 7, 8, 14, 28, 56

[tex]\dfrac{72}{56}=\dfrac{9}{7}[/tex]

6. [tex]\dfrac{54}{63}[/tex]    

Factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54

Factors of 63 = 1, 3, 7, 9, 21, 63

[tex]\dfrac{54}{63}=\dfrac{6}{7}[/tex]

Hence, this is the required solution.
