It takes Pam 45 minutes to drive to work and 60 minutes to drive home from work. Write the ratio of the time Pam spends driving home from work to the time she spends driving to work in three different ways.
60:45
to get other forms, multiply or divide the two numbers by the same amount.
The ratio of the time Pam spends driving home from work to the time she spends driving to work can be written in three different ways:
1. As a fraction: 60/45
2. As a ratio: 60:45
3. As a division: 60 ÷ 45
To write the ratio of the time Pam spends driving home from work to the time she spends driving to work, we need to compare the two times.
One way to express the ratio is using the format "a:b," where a represents the time spent driving home and b represents the time spent driving to work.
1. Ratio using minutes:
The time Pam spends driving home from work is 60 minutes, and the time she spends driving to work is 45 minutes.
Therefore, the ratio of the time Pam spends driving home to the time she spends driving to work is 60:45.
2. Ratio using fractions:
To write the ratio using fractions, we need to convert the minutes into a common unit. Let's convert both times to hours.
Pam spends 60 minutes driving home, which is equivalent to 1 hour (60/60 = 1).
Pam spends 45 minutes driving to work, which is equivalent to 0.75 hours (45/60 = 0.75).
Now we can write the ratio using fractions: 1:0.75.
3. Simplified ratio:
To simplify the ratio, we can divide both numbers by their greatest common divisor. In this case, the greatest common divisor of 60 and 45 is 15.
Dividing 60 by 15 gives 4, and dividing 45 by 15 gives 3.
So, the simplified ratio is 4:3.
