Question

Determine whether each ratio or rate is proportional. Explain your reasoning and write the proportion. 15 songs for $5; 45 songs for $15

Answer 1

Given

15 songs for $5; 45 songs for $15

Procedure

Let's calculate the fraction associated with the two ratios given to us.

`\frac{15\text{ songs}}{5\text{ \$}}=3\text{ songs/\$}`
`\frac{45\text{ songs}}{15\text{ \$}}=3\text{ songs/\$}`

In this case, we can see that the two fractions have the same ratio, therefore they have the same proportion.
