$$3.00 % =\frac{ x }{ 125 }x100%$$

fanduekisses · Answer

$$3.00percent =\frac{ x }{ 125 }100 percent $$

fanduekisses · Answer

I get 3.75 but the answer key says its 0.375

anonymous · Answer

move the decimal place over 1

fanduekisses · Answer

like 3.00 becomes 30.0 and 100 becomes 1000?

anonymous · Answer

yeah but move it over to the left instead of right

fanduekisses · Answer

that still gives me 3.75 not 0.375

anonymous · Answer

wait move it over two times to the left so that the . is in front of the 3

fanduekisses · Answer

why?

freckles · Answer

so the question is solve the following for x:
$$3.00\%=\frac{x}{125}100\%$$

freckles · Answer

you are right 3.75 should be the answer
$$125 \text{ g solution } \cdot \frac{3  \text{  g NaCl }}{100 \text{ g solution}} \ =125 \cancel{g solution} \cdot \frac{3 \text{ g NaCl}}{100  \cancel{\text{g solution}}} \ =\frac{125 \cdot 3 }{100 } \text{ g NaCl } \  \ =\frac{375}{100 } \text{ g NaCl} \ =3.75  \text{ g NaCl}$$
