Can you add fractions with unlike denominators directly?

• Yes, you can add them directly.

• No, you cannot add fractions with unlike denominators directly. You must first find a common denominator.

• You can add them if they are both improper fractions.

• You can add them if you convert them to decimals.

What is the importance of finding a common denominator?

• It allows you to accurately add or subtract fractions by ensuring that the fractions are expressed in terms of the same whole.

• It simplifies the fractions to their lowest terms.

• It helps in converting fractions to decimals easily.

• It makes it easier to compare different fractions.

What is the rule for subtracting fractions?

• To multiply the fractions and then add the numerators.

• To find a common denominator, convert the fractions, and then subtract the numerators.

• To add the denominators and keep the numerators the same.

• To convert the fractions to decimals and then subtract.

What is the process to convert @@\frac{3}{4}@@ to an equivalent fraction with a denominator of 20?

• Multiply both the numerator and denominator by 4: @@\frac{3 \times 4}{4 \times 4} = \frac{12}{16}@@

• Multiply both the numerator and denominator by 5: @@\frac{3 \times 5}{4 \times 5} = \frac{15}{20}@@

• Multiply both the numerator and denominator by 3: @@\frac{3 \times 3}{4 \times 3} = \frac{9}{12}@@

• Multiply both the numerator and denominator by 2: @@\frac{3 \times 2}{4 \times 2} = \frac{6}{8}@@

What is the least common denominator (LCD)?

• The largest multiple that two or more denominators share.

• The smallest multiple that two or more denominators share.

• The sum of two denominators.

• The difference between two denominators.

How do you add fractions with unlike denominators?

• Find a common denominator, convert each fraction to an equivalent fraction with that denominator, and then add the numerators.

• Simply add the numerators and denominators directly.

• Multiply the denominators and add the numerators.

• Convert the fractions to decimals and then add them.

What does it mean to have unlike denominators?

• Unlike denominators are denominators that are not the same. For example, in @@\frac{1}{2}@@ and @@\frac{1}{3}@@, the denominators 2 and 3 are unlike.

• Unlike denominators are denominators that are the same, such as in @@\frac{1}{2}@@ and @@\frac{1}{2}@@.

• Unlike denominators refer to fractions that cannot be simplified further.

• Unlike denominators are fractions that have a common multiple.
