Let's break down the ratio in more detail.
1. **As a fraction**:
We express the combined number of quarters and pennies as a fraction of the number of dimes:
\[
\frac{{22 \text{ quarters} + 18 \text{ pennies}}}{{35 \text{ dimes}}}
\]
This fraction represents the comparison of the total value of quarters and pennies to the value of dimes.
2. **Using "to"**:
We state the ratio using "to" to show the relationship between the combined number of quarters and pennies and the number of dimes:
\[
(22 \text{ quarters} + 18 \text{ pennies}) \text{ to } 35 \text{ dimes}
\]
This format emphasizes the comparison between the two quantities.
3. **Using a colon**:
Using a colon, we present the ratio as a pair of numbers separated by a colon:
\[
(22 \text{ quarters} + 18 \text{ pennies}) : 35 \text{ dimes}
\]
Here, the colon signifies the comparison between the combined number of quarters and pennies and the number of dimes.
