Question

Determine whether each ratio or rate is proportional. Explain your reasoning and write the proportion.15 out of 20 students are girls; 105 out of 160 students are girls

Answer 1

Find the ratio given in each situation, if it is not the same, then the ratios are not proportional:

`(20)/(15)=(4)/(3)=1.25`
`(160)/(105)=(32)/(21)=1.52`

These ratios are not equal, which means that they are not proportional.
