my answer: 0.87 x 7 = 6.09 m

    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.
