Question

A tourist from Mexico is vacationing in the U.S. One day, he notices that gas cost 2.82 dollars per gallons. On that same day, 1 peso is worth 0.053 dollars. First fill in two blanks on the left side of the equation using two of the ratios. Then write answer rounded to the nearest hundredth on the right side of the equation

Answer 1

Given hat

`\begin{gathered} 1gal=3.79L \\ and \\ 1peso=0.053dollars \\ \Rightarrow(1gal)/(3.79L)=1 \\ and \\ (1peso)/(0.053dollars)=1 \end{gathered}`

Therefore,

`\begin{gathered} (2.82dollars)/(1gal)*1*1=(2.82dollars)/(1gal)*(1gal)/(3.79L)*(1peso)/(0.053dollars)=(2.82)/(3.79*0.053)(peso)/(L) \\ =14.04(peso)/(L) \end{gathered}`

Thus, the answers ar, left to right,

1gal/3.79L, 1peso/0.053dollars, 14.04pesos/L
