Explanation
you can solve this by using a rule of three.
Step 1
if
[tex]\begin{gathered} 76\text{ passengers}\Rightarrow\text{ 2 buses} \\ so,\text{ the proportion is} \\ P=\frac{Numbe\text{r of passengers}}{\text{Number of buses}}=\frac{76\text{ pas}}{2\text{ bu}}=38\text{ passenger per bus} \end{gathered}[/tex]now
Let x represents the missing number
[tex]\begin{gathered} P_2=\frac{38\text{ passengers}}{x} \\ as\text{ the proportion is the same} \\ \frac{38}{x}=38\text{ passengers per bus} \\ x=1 \end{gathered}[/tex]so, the missing number is 1
