How do you represent sharing in fractions?

• By dividing a whole into equal parts, for example, each child gets @@\frac{2}{3}@@ of a sandwich.

• By adding the total number of items together.

• By multiplying the number of items by the number of people sharing.

• By taking the average of the items shared.

What is the relationship between fractions and division?

• Fractions can be understood as multiplication.

• Fractions can be understood as addition.

• Fractions can be understood as division. For example, @@\frac{3}{4}@@ can be interpreted as 3 divided by 4.

• Fractions can be understood as subtraction.

What is a mixed number?

• A whole number combined with a proper fraction, such as @@2 \frac{1}{4}@@.

• A number that is only a whole number without any fractions.

• A fraction that has a numerator larger than its denominator.

• A decimal number that represents a part of a whole.

What is the process to find a common denominator?

• Identify the least common multiple (LCM) of the denominators.

• Add the denominators together to get a new denominator.

• Multiply the denominators to find a common denominator.

• Choose the largest denominator as the common denominator.

How do you subtract fractions with the same denominator?

• Subtract the numerators and keep the denominator the same, e.g., @@\frac{5}{8} - \frac{3}{8} = \frac{5-3}{8} = \frac{2}{8}@@.

• Add the numerators and keep the denominator the same.

• Multiply the numerators and keep the denominator the same.

• Subtract the denominators and keep the numerator the same.

What is the difference between a proper fraction and an improper fraction?

• A proper fraction has a numerator smaller than the denominator (e.g., @@\frac{3}{4}@@), while an improper fraction has a numerator larger than or equal to the denominator (e.g., @@\frac{5}{4}@@).

• A proper fraction has a numerator larger than the denominator, while an improper fraction has a numerator smaller than the denominator.

• Both proper and improper fractions have numerators that are equal to the denominators.

• A proper fraction is always a whole number, while an improper fraction is a decimal.

How do you find the difference between two fractions?

• Ensure they have a common denominator, then subtract the numerators.

• Add the numerators and denominators together.

• Multiply the fractions and then subtract the result from one of the fractions.

• Convert the fractions to decimals and then subtract.

What is the meaning of 'combined fraction'?

• A combined fraction refers to the total amount when adding two or more fractions together. For example, if Darrell ate @@\frac{2}{9}@@ and Nani ate @@\frac{3}{9}@@, the combined fraction is @@\frac{5}{9}@@.

• A combined fraction is a fraction that is formed by multiplying two fractions together.

• A combined fraction is a fraction that represents the average of two or more fractions.

• A combined fraction is a fraction that is simplified to its lowest terms.

How do you add fractions with different denominators?

• Find a common denominator, convert the fractions, and then add the numerators.

• Add the numerators and denominators directly without finding a common denominator.

• Multiply the denominators and add the numerators.

• Subtract the smaller fraction from the larger one.

What does it mean to simplify a fraction?

• It means to convert the fraction into a decimal.

• It means to reduce the fraction to its lowest terms.

• It means to multiply the numerator and denominator by the same number.

• It means to add the numerator and denominator together.
