Unit fractions are fractions where the numerator is always 1. In representing a fraction, we can break it down into a sum of unit fractions. For example, if we have the fraction 3/4, we can represent it as 1/4 + 1/4 + 1/4. This helps us understand the concept of fraction addition.
To convert an addition expression into a multiplication expression, we count the number of terms in the addition expression and write it as a product. For example, if we have the addition expression 1/4 + 1/4 + 1/4, we can write it as (1/4) x (3), which simplifies to (3/4).
To find the final answer using both addition and multiplication expressions, we can first use the addition expression to find the sum of the fractions. Then, we can use the multiplication expression to directly find the product of the fractions. Comparing both results helps us understand the relationship between addition and multiplication.
