Given,
the ratio of height of a bonsai tree to a full-size ficus tree is 1:9
Bonsi ficus tree = 6 inches
Let,
the height of full size ficus tree be "x"
Then,
Using ratio and proportion, we can write,
[tex] \frac{1}{9} = \frac{6}{x} [/tex]
[tex] \frac{1}{9}*x = 6 [/tex]
[tex]x = 6*{ \frac{9}{1}} [/tex]
[tex]x = 54[/tex]
So, the height of the full-size ficus is 54 inches
