AFirst develop your ratio:
\(\frac{x}{14} = \frac{8.70}{19.46}\)
where \(x\) is the amount of gas needed.

 Divide the amount charged for \(x\) amount of gas by 19.46, then multiply that amount by 14 to get the amount of gas bought: \(\frac{6.26}{14} = \frac{8.70}{19.46}\)

B. Again, develop your ratio:
\(\frac{9.5}{14} = \frac{x}{19.46}\)
and use the same procedure.
 
 Divide 9.5 by 14, then multiply your answer by 19.46 to get:
\(\frac{9.5}{14} = \frac{13.21}{19.46}\)

\(a) 14:19.46 \$ = x :8.70 \$ \\ \\ x=\frac{14*8.70}{19.46}= \frac{121.8}{19.46} \\ \\ \boxed{x=6.258} \\ \\ b)14:19.46 \$= 9.5:x \\ \\ x=\frac{19.46*9.5}{14}= \frac{184.87}{14} \\ \\ \boxed{x=13.205}\)
