Q: What is a fraction?
A: A fraction is a number that represents a part of a whole.
Q: What is the numerator of a fraction?
A: The numerator is the top part of a fraction that represents the number of parts we have.
Q: What is the denominator of a fraction?
A: The denominator is the bottom part of a fraction that represents the total number of equal parts.
Q: How do you add fractions?
A: To add fractions with the same denominator, add their numerators and keep the same denominator.
Q: How do you subtract fractions?
A: To subtract fractions with the same denominator, subtract their numerators and keep the same denominator.
Q: How do you multiply fractions?
A: To multiply fractions, multiply the numerators and multiply the denominators.
Q: How do you divide fractions?
A: To divide fractions, multiply the first fraction by the reciprocal of the second fraction.
Q: What is a mixed number?
A: A mixed number is a whole number combined with a fraction.
Q: What is an improper fraction?
A: An improper fraction is a fraction where the numerator is greater than or equal to the denominator.
Q: How do you convert an improper fraction to a mixed number?
A: Divide the numerator by the denominator. The quotient becomes the whole number part and the remainder becomes the numerator of the fraction part.
Q: How do you convert a mixed number to an improper fraction?
A: Multiply the whole number by the denominator and add the numerator. This sum becomes the numerator of the improper fraction, with the denominator staying the same.
Q: What is a common denominator?
A: A common denominator is a shared multiple of the denominators of two or more fractions.
Q: How do you find a common denominator?
A: To find a common denominator, you can multiply the denominators together or find the least common multiple (LCM) of the denominators.
Q: What is the least common denominator (LCD)?
A: The least common denominator (LCD) is the smallest common multiple of the denominators of two or more fractions.
Q: How do you simplify a fraction?
A: To simplify a fraction, find the greatest common factor (GCF) of the numerator and denominator and divide both by it.
Q: What is an equivalent fraction?
A: An equivalent fraction is a fraction that represents the same value, but has different numerators and denominators.
Q: What is a decimal?
A: A decimal is a number written using tenths, hundredths, thousandths, etc., separated by a decimal point.
Q: How do you convert a fraction to a decimal?
A: Divide the numerator by the denominator using long division or a calculator.
Q: What is a percent?
A: A percent is a number out of 100, often represented with the % symbol.
Q: How do you convert a fraction to a percent?
A: Divide the numerator by the denominator and multiply by 100.
Q: How do you convert a percent to a decimal?
A: Divide the percent by 100 or move the decimal point two places to the left.
Q: How do you convert a decimal to a percent?
A: Multiply the decimal by 100 or move the decimal point two places to the right.
