Compare proportions from descriptions & Tables test
1. The strawberry plant grows at a slower rate because it grows 0.8 inches per day while the bean plant grows 1 inch per day
2. The baby slept fewer hours per day than the cat
3. company B has the best hourly rate of $28.50/hour.
4. Maribella spends less time on homework per night
compared to her classmates, spending only 1 hour while the average is 2 hours.
5. In a survey, 60% of respondents prefer coffee over tea.
6. The annual sales for Company A were $1 million, while the annual sales for Company B were $2 million, indicating a higher proportion for Company B.
7. The percentage of students who passed the exam in the first attempt was 85%, higher than the 75% pass rate in the previous year.

1. To compare the proportions of growth rates between the strawberry plant and the bean plant, we need to calculate the ratio of their growth rates.
For the strawberry plant: 0.8 inches/day
For the bean plant: 1 inch/day
The ratio of the strawberry plant's growth rate to the bean plant's growth rate is 0.8/1 = 0.8.
Therefore, the strawberry plant grows at a rate that is 0.8 times slower than the bean plant.
2. To compare the proportions of sleep hours between the baby and the cat, we need to know the specific sleep hours for each.
Unfortunately, the description only states that the baby slept fewer hours per day than the cat, but it does not provide exact numbers. Without that information, we cannot compare the proportions of sleep hours accurately.
3. To compare the hourly rates of company B and another company, we need to know the hourly rate of the other company.
Since we only have information about company B's hourly rate, which is $28.50/hour, without information about other companies, we cannot compare the proportions of hourly rates.
4. To compare the proportions of time spent on homework between Maribella and someone else, we need to know the actual amount of time spent.
Unfortunately, the description only says that Maribella spends less time on homework per night, but it does not provide specific numbers. Without that information, we cannot compare the proportions accurately.
To compare proportions from descriptions and tables, you need to analyze the information provided and identify the key components for comparison. Let's break down each situation:
1. The strawberry plant grows at a slower rate because it grows 0.8 inches per day while the bean plant grows 1 inch per day:
To compare proportions, you need to calculate the ratio between the growth rates of the two plants. In this case, the ratio would be 0.8 inches/day for the strawberry plant and 1 inch/day for the bean plant. To simplify the ratio, you can express it as 0.8:1 or 4:5. This means that for every 4 parts of growth the strawberry plant has, the bean plant has 5 parts of growth.
2. The baby slept fewer hours per day than the cat:
To compare proportions, you need to compare the number of hours the baby sleeps with the number of hours the cat sleeps. If the baby sleeps 10 hours per day, for example, and the cat sleeps 12 hours per day, you can express the ratio as 10:12 or simplify it to 5:6. This means that for every 5 parts of sleep the baby has, the cat has 6 parts of sleep.
3. Company B has the best hourly rate of $28.50/hour:
To compare proportions, you need to compare the hourly rates of each company. If the hourly rates for the other companies are lower than $28.50, then Company B indeed has the best rate. If there are more companies and their hourly rates are provided, you can compare them individually to determine which has the highest or lowest rate.
4. Maribella spends less time on homework per night:
To compare proportions, you need to compare the time Maribella spends on homework with someone else's time. Without specific details or values provided, it's difficult to determine an exact comparison. However, if Maribella's friend spends 2 hours on homework, and Maribella spends 1.5 hours, you can express the ratio as 1.5:2 or simplify it to 3:4. This means that for every 3 parts of time Maribella spends on homework, her friend spends 4 parts of time.
Overall, when comparing proportions from descriptions and tables, pay attention to the numerical values provided and determine the ratio between the quantities being compared.
