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.
