A survey determines that 100 of 480 students ride the bus to PPCC each day. If this ratio holds in a math class with 24 students, how many of the math students ride the bus to PPCC

Respuesta :

Step 1

Write the ratio equation that can be used to solve the problem.

[tex]\frac{students\text{ that ride the bus to PPCC daily }}{\text{Total number of students}}=\frac{x}{\text{number of students in the maths class}}[/tex]

Students that ride the bus to PPCC daily = 100

Total number of students = 480

x = number of maths students that ride the bus to PPCC

Number of students in the maths class = 24

Step 2

Substitute and get the required answer.

[tex]\begin{gathered} \frac{100}{480}=\frac{x}{24} \\ 2400\text{ = 480x} \\ x\text{ = }\frac{2400}{480}=5 \\ x=5 \end{gathered}[/tex]

Hence, the number of maths students that ride the bus to PPCC is 5
