kittiwitti1 · Answer

So, 6.5 oz baking soda per 200 loaves
Put it in fraction form as a ratio$$\frac{6.5}{200}$$

anonymous · Answer

=0.0325

kittiwitti1 · Answer

No, no simplifying. It's just a ratio.
The problem is asking for how many oz. of baking soda we need for THIRTY loaves...
Proportion:$$\frac{6.5}{200}=\frac{x}{30}$$Do you know how to solve a proportion?

anonymous · Answer

find the common denomenator right?

kittiwitti1 · Answer

Well... I don't know about that method, but I would cross-multiply.

anonymous · Answer

or we can use 1 for x right?

anonymous · Answer

anonymous · Answer

195/30 =6.5 oz
