An engine runs on 0.1 quart of oil for every 3.5 quarts of gasoline. You make 3 quarts of the mixture. How much oil and gasoline do you use?
If you mix 0.1 quart of oil for every 3.5 quarts of gasoline, you total mixture will be 3.6 quarts.
The percentage of oil is 0.1 / 3.6 = 0.0277777...
The percentage of gasoline is 3.5 / 3.6 = 0.9722222 ...
If there are 3 quarts of the mixture,
the amount of oil is 3 x 0.277777 = 0.0833333 quarts
the amount of gasoline is 3 x 0.972222 = 2.9166667 quarts.

Hello Guest!
\(x\cdot(3.5+0.1)=1\)
\(x=\frac{1}{3.5+0.1}=\color{blue}\frac{1}{3.6}\)
\(\frac{1}{3.6}\cdot(3.5+0.1)=\\ 0,97\overline 2+0,02\overline7=1\\ \times 3=\\ \color{blue}\ 2.91\overline6+0.08\overline3=3\)
