- How do I find the first 5 multiples of a number?
- To find the first 5 multiples of a number, you simply multiply the number by 1, 2, 3, 4, and 5.
- What is the decimal representation of 2 as a fraction?
- The decimal representation of 2 as a fraction is 0.002 when expressed as 2/1000.
- How do I reduce a fraction to its lowest terms?
- To reduce a fraction to its lowest terms, divide the numerator and denominator by their greatest common divisor (GCD).
- How do I find the Least Common Multiple (LCM) of two numbers?
- To find the LCM of two numbers, determine the smallest number that is a multiple of both numbers.
- How do I find the Highest Common Factor (HCF) of two numbers?
- To find the HCF of two numbers, determine the largest number that divides both numbers evenly.
- What are prime factors, and how do I express a number as a product of its prime factors?
- Prime factors are the prime numbers that multiply together to give the original number. To express a number as a product of its prime factors, factorize the number into prime numbers.
- How do I identify factors of a number?
- Factors of a number are the numbers that divide the given number evenly without leaving a remainder.
- What are the different types of fractions?
- Two types of fractions are proper fractions (where the numerator is less than the denominator) and improper fractions (where the numerator is equal to or greater than the denominator).
- How do I convert mixed fractions to improper fractions?
- To convert a mixed fraction to an improper fraction, multiply the whole number by the denominator and add the numerator. The result becomes the new numerator, and the denominator remains unchanged.
- How do I perform basic arithmetic operations with decimals and fractions?
- To perform arithmetic operations with decimals and fractions, convert them to a common format (either all decimals or all fractions), perform the operation, and then convert the result back to the desired format if necessary.
