Identity Property of Multiplication
Apply the identity property of multiplication in Grade 6 math — understand that multiplying any number by 1 leaves it unchanged, and use this property to rename fractions.
Key Concepts
Property The Identity Property of Multiplication states that if one of two factors is 1, the product equals the other factor. So, $a \times 1 = a$.
Examples Multiplying by 1 directly: $\frac{3}{4} \times 1 = \frac{3}{4}$ Multiplying by a fraction equal to 1: $\frac{1}{2} \times \frac{2}{2} = \frac{2}{4}$ Using the property to rename a fraction: $\frac{3}{5} \times \frac{4}{4} = \frac{12}{20}$.
Explanation Multiplying any number by 1 is like looking in a mirror—it doesn't change! The fun trick is that '1' can dress up as any fraction where the top and bottom match, like $\frac{5}{5}$. This helps us rename other fractions without changing their value.
