Question 1: What are fractions?
Answer: Fractions are numbers that represent part of a whole. They are written in the form of a/b, where a is the numerator and b is the denominator. The numerator is the number of parts being considered and the denominator is the total number of parts that make up the whole. For example, if you have a pizza that is cut into 8 slices, each slice is 1/8 of the pizza.
Question 2: How do you divide whole numbers by fractions?
Answer: To divide whole numbers by fractions, you must first convert the fraction to an equivalent fraction with a denominator of 1. To do this, you must multiply the numerator and denominator of the fraction by the same number. Once the fraction has been converted to an equivalent fraction with a denominator of 1, you can then divide the whole number by the numerator of the fraction.
Question 3: What is an example of dividing whole numbers by fractions?
Answer: An example of dividing whole numbers by fractions is dividing 8 by 3/4. To solve this problem, you must first convert the fraction to an equivalent fraction with a denominator of 1. To do this, you must multiply the numerator and denominator of the fraction by the same number. In this case, you would multiply the numerator and denominator by 4. This would give you 3/4 x 4/4, which is equivalent to 12/4. Now that the fraction has been converted to an equivalent fraction with a denominator of 1, you can divide the whole number by the numerator of the fraction. In this case, you would divide 8 by 12, which is equal to 2/3.
Question 4: What is the difference between a proper fraction and an improper fraction?
Answer: The main difference between a proper fraction and an improper fraction is that a proper fraction has a numerator that is less than its denominator, while an improper fraction has a numerator that is greater than or equal to its denominator. For example, 1/2 is a proper fraction, while 5/2 is an improper fraction.
Question 5: How do you divide a whole number by a mixed number?
Answer: To divide a whole number by a mixed number, you must first convert the mixed number to an improper fraction. To do this, you must multiply the denominator of the fraction part of the mixed number by the whole number part of the mixed number, and then add the numerator of the fraction part of the mixed number to the product. Once the mixed number has been converted to an improper fraction, you can then divide the whole number by the numerator of the fraction.
Question 6: What is the inverse operation of division?
Answer: The inverse operation of division is multiplication. This means that if you have a division problem, you can solve it by multiplying the two numbers together. For example, if you have the problem 8/4, you can solve it by multiplying 8 and 4 together, which would give you the answer 32.
Question 7: How do you divide a fraction by a fraction?
Answer: To divide a fraction by a fraction, you must first convert the fractions to equivalent fractions with a common denominator. To do this, you must multiply the numerator and denominator of each fraction by the same number. Once the fractions have been converted to equivalent fractions with a common denominator, you can then divide the numerators of the fractions.
Question 8: What is the difference between a reciprocal and a fraction?
Answer: The main difference between a reciprocal and a fraction is that a reciprocal is the inverse of a fraction, while a fraction is a number written in the form of a/b, where a is the numerator and b is the denominator. For example, if you have the fraction 3/4, then its reciprocal is 4/3.
Question 9: How do you divide a fraction by a whole number?
Answer: To divide a fraction by a whole number, you must first convert the fraction to an equivalent fraction with a denominator of 1. To do this, you must multiply the numerator and denominator of the fraction by the same number. Once the fraction has been converted to an equivalent fraction with a denominator of 1, you can then divide the numerator of the fraction by the whole number.
Question 10: How do you divide a whole number by a decimal?
Answer: To divide a whole number by a decimal, you must first convert the decimal to a fraction. To do this, you must move the decimal point to the right until it is a whole number, and then count the number of places the decimal point was moved. The whole number is the numerator of the fraction and the number of places the decimal point was moved is the denominator of the fraction. Once the decimal has been converted to a fraction, you can then divide the whole number by the numerator of the fraction.
Question 11: What is the difference between a fraction and a ratio?
Answer: The main difference between a fraction and a ratio is that a fraction is a number written in the form of a/b, where a is the numerator and b is the denominator, while a ratio is a comparison of two numbers written in the form of a:b. For example, if you have the fraction 3/4, then its ratio would be 3:4.
Question 12: How do you divide a fraction by a mixed number?
Answer: To divide a fraction by a mixed number, you must first convert the mixed number to an improper fraction. To do this, you must multiply the denominator of the fraction part of the mixed number by the whole number part of the mixed number, and then add the numerator of the fraction part of the mixed number to the product. Once the mixed number has been converted to an improper fraction, you can then divide the numerator of the fraction by the numerator of the fraction part of the mixed number.
Question 13: How do you divide a fraction by a negative number?
Answer: To divide a fraction by a negative number, you must first convert the fraction to an equivalent fraction with a denominator of 1. To do this, you must multiply the numerator and denominator of the fraction by the same number. Once the fraction has been converted to an equivalent fraction with a denominator of 1, you can then divide the numerator of the fraction by the negative number.
