Question

16 emails to 6 text messages- 10 emails to 4 text messages proportional or not

Answer 1

Given:

16 emails to 6 text messages- 10 emails to 4 text messages

To find:

Whether 16 emails to 6 text messages- 10 emails to 4 text messages proportional or not.

Solution:

Check the ratio of emails to text. If the ratios are equal then the relation is proportional.

16 emails to 6 text messages.

$\dfrac{Emails}{Text}=\dfrac{16}{6}$

$\dfrac{Emails}{Text}=\dfrac{8}{3}$

$\dfrac{Emails}{Text}=8:3$

10 emails to 4 text messages.

$\dfrac{Emails}{Text}=\dfrac{10}{4}$

$\dfrac{Emails}{Text}=\dfrac{5}{2}$

$\dfrac{Emails}{Text}=5:2$

Since $\dfrac{8}{3}\neq \dfrac{5}{2}$ or $8:3\neq 5:2$, therefore, it is not proportional.
