# Multiply Unit Fractions by Whole Number

- Grade 4 MathExtend the understanding of multiplication to fractions. Multiplication can be thought of as a process of combining (summing up) several copies of a number. Extending this line of thinking to fractions, one can visualize a fraction n*/b* as *n* copies of the unit fraction *1/b. *For example,* *students reason that the fraction 3/4 can be thought of as *1/4 + 1/4 + 1/4* or *3 x (1/4). *In **Multiply Unit Fractions by a Whole Worksheet**, students begin by visualizing multiplication of unit fractions by whole using models, before moving on to direct multiplication.
