What is a ratio?

A ratio is a comparison of two quantities expressed as a quotient or fraction, indicating how many times one quantity is contained within another. It is used to show the relationship between the sizes, amounts, or values of different quantities.

How do you find the area of a rectangle?

To find the area of a rectangle, you multiply the length of the rectangle by its width. The formula for calculating the area of a rectangle is: Area = length x width.

What is the difference between a prime number and a composite number?

A prime number is a number greater than 1 that is only divisible by 1 and itself, such as 2, 3, 5, 7, while a composite number is a number greater than 1 that has more than two factors, such as 4, 6, 8, 9.

How do you solve one-step equations?

To solve one-step equations, you need to isolate the variable by using inverse operations. This means doing the opposite operation to both sides of the equation. For example, if the equation is 2x + 3 = 11, you would first subtract 3 from both sides to get 2x = 8, and then divide by 2 to solve for x, which gives you x = 4. Just remember to perform the same operation on both sides of the equation to maintain balance and find the correct solution.

What is the formula for finding the circumference of a circle?

The formula for finding the circumference of a circle is C = 2?r, where C represents the circumference and r represents the radius of the circle.

How do you calculate the mean of a set of numbers?

To calculate the mean of a set of numbers, add up all the numbers in the set and then divide the sum by the total number of values in the set. This will give you the average or mean of the set of numbers.

What is the Pythagorean theorem?

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it can be represented as a^2 + b^2 = c^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

How do you simplify fractions?

To simplify a fraction, you divide the numerator and the denominator by their greatest common factor (GCF). By finding the largest number that evenly divides both the numerator and denominator, you can reduce the fraction to its simplest form. Simplifying fractions helps to make them easier to work with and compare in calculations.

What is the formula for finding the volume of a rectangular prism?

The formula for finding the volume of a rectangular prism is V = l x w x h, where V represents the volume, l is the length, w is the width, and h is the height of the prism.

How do you find the probability of an event?

To find the probability of an event, you divide the number of favorable outcomes by the total number of possible outcomes. This is represented as a fraction, decimal, or percentage, with probabilities ranging from 0 (impossible event) to 1 (certain event). The higher the probability, the more likely the event is to occur.
