the roots of a tree are 1/8 of the tree. they are 0.87 m. how tall is the tree?
my answer: 0.87 x 7 = 6.09 m
please check if my answer is right
thanks :)

Why did you multiply 0.87 by 7?
1/8x = 0.87
0.125x = 0.87
x = 0.87 / 0.125
x = 6.96 m 
I am not trying to fin out x. Its the multiplication sign: 0.87 multiplied by 7.
how did you get 0.125 in the question? 
I changed 1/8 to its equivalent decimal, 0.125.
I used x for the height of the tree. 
1 divided by 8 = 0.125
0.125 divided by 0.87 = 6.96
k so the answer is 6.96 m
ps:
are u sure:) 
Let's prove it. Is 1/8 of 6.96 = 0.87
0.125 * 6.96 = 0.87
Yep! It's right. 
thank you so much :)

You're very welcome.
