What is a fraction?
A fraction is a mathematical expression representing a part of a whole, consisting of a numerator (the top number) and a denominator (the bottom number) separated by a horizontal line. It indicates how many parts of a whole are being considered, with the numerator representing the parts being looked at and the denominator representing the total number of parts that make up the whole.
Define perimeter and provide an example.
Perimeter is the total distance around the outer boundary of a shape. It is calculated by adding together the lengths of all the sides of the shape. For example, the perimeter of a rectangle with sides of 5 cm and 8 cm would be 5 + 5 + 8 + 8 = 26 cm.
What is the difference between a prime and a composite number?
A prime number is a positive integer greater than 1 that has only two factors: 1 and itself, while a composite number is a positive integer greater than 1 that has more than two factors, meaning it can be divided evenly by at least one other number in addition to 1 and itself.
Explain how to multiply two-digit numbers.
To multiply two-digit numbers, place the numbers vertically, aligning the rightmost digit of the bottom number with the rightmost digit of the top number. Multiply the rightmost digit of the bottom number with each digit of the top number, starting from the right, and write the results below each corresponding digit of the top number. Repeat this process for the leftmost digit of the bottom number. Finally, add all of the results to get the final product. Carry over any tens to the left.
What is a factor and how do you find the factors of a number?
A factor of a number is an integer that can be multiplied to obtain that number. To find the factors of a number, you can list all the numbers that divide the given number evenly with no remainder, starting from 1 up to the number itself. Alternatively, you can use prime factorization by breaking down the number into a product of prime numbers to determine all possible factors.
Define area and provide an example.
Area is the measurement of the surface enclosed by a geometric shape, typically expressed in square units. For example, the area of a rectangle can be calculated by multiplying its length and width. If a rectangle has a length of 5 units and a width of 3 units, the area would be 5 units x 3 units = 15 square units.
How do you add and subtract fractions with unlike denominators?
To add or subtract fractions with unlike denominators, first find the least common multiple (LCM) of the denominators. Then, rewrite each fraction with the LCM as the common denominator. Once the fractions have the same denominator, you can simply add or subtract the numerators while keeping the common denominator the same. Finally, simplify the resulting fraction if needed by finding the greatest common factor (GCF) of the numerator and denominator and dividing both by it.
Explain how to divide a three-digit number by a one-digit number.
To divide a three-digit number by a one-digit number, you would start by placing the three-digit number inside the division bracket and the one-digit number outside. Next, you would divide the first digit of the three-digit number by the one-digit number, which gives you the quotient. Place this quotient over the first digit of the three-digit number. Multiply the one-digit number by the quotient, and subtract this result from the first three-digit number to get the remainder. Bring down the next digit of the three-digit number and repeat the process until you have divided the entire three-digit number by the one-digit number.
What are the properties of addition and multiplication?
The properties of addition and multiplication are commutative, associative, distributive, and have an identity element. The commutative property states that the order of the numbers does not affect the result, the associative property states that the grouping of numbers does not affect the result, and the distributive property reflects how multiplication distributes over addition. The identity element for addition is 0, as adding 0 to any number leaves it unchanged, while for multiplication, it is 1, as multiplying any number by 1 leaves it unchanged.
Define probability and explain how to calculate it.
Probability is a measure of the likelihood of a particular event occurring, expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. To calculate probability, you can use the formula: Number of successful outcomes / Total number of possible outcomes. For example, if you want to calculate the probability of rolling a 6 on a fair six-sided die, there is only one successful outcome (rolling a 6) out of six possible outcomes (1, 2, 3, 4, 5, 6), so the probability would be 1/6 or approximately 0.167.
