To find the ratio of boys to girls in Antonio's math class, you compare the number of boys to the number of girls.
There are 18 boys and 14 girls, so the ratio of boys to girls can be expressed as:
\[ \text{Ratio} = \frac{\text{Number of boys}}{\text{Number of girls}} = \frac{18}{14} \]
This simplifies to:
\[ \text{Ratio} = \frac{9}{7} \]
However, looking at the options provided, the ratio is commonly expressed in the form of "boys to girls":
So the correct answer is 18 to 14.
To find the part of the whole ratio for chocolate ice cream in Samantha's class, we first need to determine the total number of students surveyed. We can do this by adding the counts for each type of ice cream:
Now we add these together:
\[ 8 + 12 + 3 + 9 = 32 \]
Now that we know the total number of students is 32, we can express the ratio of chocolate ice cream (which has 12) to the total (32).
The part-to-whole ratio of chocolate ice cream is:
\[ \text{Ratio of Chocolate} = \frac{\text{Number of Chocolate}}{\text{Total}} = \frac{12}{32} \]
This can also be expressed in the simplest form:
\[ 12:32 \] can be simplified to \( 3:8 \).
However, since this specific option may not be in your provided answers, the correct answer from your choices for the part of the whole ratio of chocolate ice cream is 12:32.
The problem states that for every three M&Ms in the bag, there are two blue M&Ms.
Given the ratio of blue to red M&Ms is 2:3, we can express the relationship as follows:
Now we can complete the ratio table:
To find the red M&Ms when there are 8 blue, we can set up a proportion based on the established ratio (2 blue for every 3 red):
\[ \frac{2 \text{ blue}}{3 \text{ red}} = \frac{8 \text{ blue}}{x \text{ red}} \]
Cross-multiplying gives us:
\[ 2x = 3 \times 8 \]
\[ 2x = 24 \]
Solving for \( x \):
\[ x = \frac{24}{2} = 12 \]
So for 8 blue M&Ms, there will be 12 red M&Ms.
Thus, the correct answer to complete the ratio table is 12.
To determine which ratio is greatest among \(2:3\), \(5:6\), \(14:16\), and \(21:25\), we can convert each ratio to a decimal by dividing the first number by the second number.
For \(2:3\): \[ \frac{2}{3} \approx 0.6667 \]
For \(5:6\): \[ \frac{5}{6} \approx 0.8333 \]
For \(14:16\): \[ \frac{14}{16} = \frac{7}{8} = 0.875 \]
For \(21:25\): \[ \frac{21}{25} = 0.84 \]
Now, comparing the decimal values:
The greatest ratio is \(14:16\), which simplifies to \(0.875\).
To find out how many shoppers were buying items on sale, we can use the percentage provided in the survey.
Given:
Now, we can calculate the number of shoppers buying items on sale using the formula:
\[ \text{Number of shoppers buying sale items} = \text{Total shoppers} \times \left(\frac{\text{Percentage}}{100}\right) \]
Plugging in the values:
\[ \text{Number of shoppers buying sale items} = 50 \times \left(\frac{30}{100}\right) = 50 \times 0.30 = 15 \]
So, the number of shoppers buying sale items only is 15 shoppers.
To find the percentage equivalent to the fraction \( \frac{12}{50} \), you can divide the numerator by the denominator and then multiply by 100.
Here's the calculation:
\[ \frac{12}{50} = 0.24 \]
Now, convert this to a percentage:
\[ 0.24 \times 100 = 24% \]
Thus, the percent that is equivalent to \( \frac{12}{50} \) is 24%.
