**Ms. Sue**, Wednesday, November 14, 2012 at 8:29pmWhy did you multiply 0.87 by 7?

1/8x = 0.87

0.125x = 0.87

x = 0.87 / 0.125

x = 6.96 m

**Winnie**, Wednesday, November 14, 2012 at 8:32pmI 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?

**Ms. Sue**, Wednesday, November 14, 2012 at 8:40pmI changed 1/8 to its equivalent decimal, 0.125.

I used x for the height of the tree.

**Winnie**, Wednesday, November 14, 2012 at 8:45pm1 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:)

**Ms. Sue**, Wednesday, November 14, 2012 at 8:47pmLet's prove it. Is 1/8 of 6.96 = 0.87

0.125 * 6.96 = 0.87

Yep! It's right.
