How do you add two fractions with different denominators?

To add two fractions with different denominators, first find a common denominator by determining the least common multiple of the two denominators. Then, rewrite each fraction with the common denominator and add the numerators together. Finally, simplify the resulting fraction if needed by reducing it to its simplest form.

What is the formula for finding the perimeter of a rectangle?

The formula for finding the perimeter of a rectangle is calculated by adding together the lengths of all four sides. It can be represented as 2 times the width plus 2 times the length, where the width is the shorter side and the length is the longer side of the rectangle.

How do you find the area of a triangle?

To find the area of a triangle, you can use the formula A = 1/2 * base * height, where the base is the length of the bottom side of the triangle and the height is the perpendicular distance from the base to the top vertex. Simply plug in the values for the base and height into the formula and calculate the area.

How can you determine if a number is even or odd?

You can determine if a number is even or odd by dividing it by 2. If the number divides evenly (remainder of 0), then it is even. If there is a remainder of 1, then it is odd.

What is the value of pi?

The value of pi is approximately 3.14159, with the decimal representation continuing on indefinitely without repeating.

How do you convert a fraction to a decimal?

To convert a fraction to a decimal, you simply divide the numerator (top number) by the denominator (bottom number). The result of this division will give you the decimal equivalent of the fraction. You can do this division using a calculator or long division method to get the decimal representation of the fraction.

What is the difference between prime and composite numbers?

A prime number is a positive integer greater than 1 that has exactly two distinct positive divisors: 1 and the number itself, while a composite number is a positive integer greater than 1 that has more than two distinct positive divisors. In other words, a prime number can only be divided evenly by 1 and itself, whereas a composite number can be divided evenly by at least one other number in addition to 1 and itself.

How do you find the missing side length of a right triangle using the Pythagorean theorem?

To find the missing side length of a right triangle using the Pythagorean theorem, you would square the lengths of the two known sides, then add those squares together. Next, take the square root of the sum to find the length of the missing side. This can be expressed as a formula: a² + b² = c², where 'a' and 'b' are the lengths of the two known sides and 'c' is the length of the missing side.

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

To calculate the mean of a set of numbers, you add up all the numbers in the set and then divide the sum by the total number of values in the set. This gives you the average value of the numbers in the set, which is referred to as the mean.

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 × w × h, where V represents the volume, l is the length, w is the width, and h is the height of the prism.
