What is the relationship between ratios and proportions?

Ratios compare two quantities, while proportions state that two ratios are equal. For example, if the ratio of boys to girls is 2:3, the proportion can be expressed as $$\frac{2}{3} = \frac{4}{6}$$ .

What is the formula for finding the cost per item?

To find the cost per item, divide the total cost by the number of items. For example, if 3 pens cost $0.69, the cost per pen is $$\frac{0.69}{3} = 0.23$$ .

How do you determine if two fractions are equivalent?

To determine if two fractions are equivalent, cross-multiply and check if the products are equal. For example, for $$\frac{a}{b}$$ and $$\frac{c}{d}$$ , check if $$a \cdot d = b \cdot c$$ .

A unit rate is a comparison of two different quantities when they are combined together. For example, if a car travels 300 miles in 5 hours, the unit rate is 60 miles per hour.

How can you use proportions to solve real-world problems?

Proportions can be used to solve real-world problems by setting up equations that relate different quantities, allowing you to find unknown values based on known ratios.

What is the importance of understanding proportions in math?

Understanding proportions is crucial in math as it helps in solving problems related to ratios, scaling, and real-life applications like cooking, budgeting, and measurements.

How do you check if a proportion is set up correctly?

To check if a proportion is set up correctly, ensure that the ratios being compared are relevant and that the relationship between the quantities is logical.

What is the first step in solving a proportion?

The first step in solving a proportion is to set it up correctly by identifying the two ratios that you want to compare and writing them as an equation.
