Question

In one month, Jillian made $36$ local phone calls and $20$ long distance calls.

What was her ratio of local calls to long distance calls for that month?

• A. $3:2$
• B. $9:4$
• C. $9:5$
• D. $2:1$

Answer 1

The correct option is C

$9:5$

Explanation for correct option(s):

Find the ratio of local calls to long distance calls for that month

Consider the given data as,

Total local phone calls made by the Jillian is $36$.

Total long distance phone calls made by the Jillian is $20$.

To get the value of ratio we need to know about the term "ratio".

What is the ratio?

Ratio is the relationship between the number of same unit to verify the how bigger or smaller is a number to the another when we compare two quantities to each we write them in the form of the ratio.

Now to find out the ratio of local calls to long distance calls made by Jillian in that month we need to divide the number of local calls to the number of long distance calls.

Suppose $r$ be the ratio of local calls to long distance calls made by Jillian in that month.

Thus,

$$\begin{gathered} r=\frac{36}{20} \\ r=\frac{9}{5} \end{gathered}$$

Hence, the ratio of local calls to long distance calls made by Jillian in that month is $\frac{9}{5}$ or $9:5$.

Therefore, the correct answer is option $C$.
