**jazz**, Saturday, November 1, 2008 at 8:15pmbut why does the question say "8% IS 56"? why wouldn't it say 8% OF 56?

**Writeacher**, Saturday, November 1, 2008 at 8:20pmIf it's saying "8% is 56" then your task is to find out what 100% is, I guess. So in that case, your ratio works.

If it said "8%**of**56" then 56 would be the 100% and you'd need to multiply to find what 8% is.

**Ms. Sue**, Saturday, November 1, 2008 at 8:23pmOops. I goofed. Sorry. My fingers got ahead of my brain.

I think the problem means that 8% of a number is 56 kg.

0.08 x = 56

x = 56 / 0.08

x = 700
