Given:
This table shows the ratio of apples to oranges.
Apples Oranges
6 10
9 15
12 ?
To find:
The missing value in the table of equivalent ratios.
Solution:
Let the missing value be x.
The ratios of apple and oranges are equivalent. So,
[tex]\dfrac{6}{10}=\dfrac{9}{15}=\dfrac{12}{x}[/tex]
[tex]\dfrac{3}{5}=\dfrac{3}{5}=\dfrac{12}{x}[/tex]
[tex]\dfrac{3}{5}=\dfrac{12}{x}[/tex]
On cross multiplication, we get
[tex]3\times x=12\times 5[/tex]
[tex]3x=60[/tex]
Divide both sides by 3.
[tex]x=20[/tex]
Therefore, the missing value is 20.
