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

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?

• Math URGENT! -

I changed 1/8 to its equivalent decimal, 0.125.

I used x for the height of the tree.

• Math URGENT! -

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.
