Simplify the rate 220/4
beats per 1 minute= beats per minute
The Correct Answer and Explanation is:
To simplify the rate of ( \frac{220}{4} ) beats per minute, we divide 220 by 4.
Calculation:
[
\frac{220}{4} = 55
]
Answer:
The simplified rate is 55 beats per minute.
Explanation:
When dealing with rates, such as beats per minute, it is often necessary to simplify the fraction to understand the average or typical value represented by the rate. In this case, we started with ( \frac{220}{4} ) beats per minute. This fraction represents a situation where there are 220 beats occurring over a span of 4 minutes.
Step 1: Understanding the Numerator and Denominator
- The numerator (220) represents the total number of beats.
- The denominator (4) represents the time span in minutes during which these beats occurred.
Step 2: Performing the Division
To simplify the rate, we divide the total number of beats by the total time:
[
\frac{220}{4} = 55
]
This tells us that, on average, there are 55 beats occurring each minute.
Step 3: Interpretation
Simplifying the rate to 55 beats per minute allows for a more straightforward understanding of how frequently beats are occurring within a one-minute interval. This is particularly useful in various fields such as music, medicine (e.g., heart rate monitoring), and physical fitness. For example, if someone is measuring their heart rate during exercise, knowing that their heart beats at a rate of 55 beats per minute gives a clear, immediate understanding of their cardiovascular activity level.
Step 4: Importance of Simplifying Rates
Simplifying rates not only makes calculations easier but also allows for better comparisons with other rates. For instance, if someone else has a heart rate of 70 beats per minute, you can quickly see that the first person’s heart rate is lower. In summary, simplifying rates provides clarity and efficiency in communication, which is vital in fields where precise measurements and comparisons are necessary.
