Evaluate the expression. 2/5 - 1/4 * 4/5 Write your answer as a fraction or as a whole or mixed number. ______

Identify operations: Step 1: Identify the operations and order of operations in the expression. We need to solve 2/5 - 1/4 * 4/5. According to the order of operations (PEMDAS/BODMAS), we first do the multiplication before subtraction. Calculation: First, multiply 1/4 by 4/5. 1/4 * 4/5 = (1*4)/(4*5) = 4/20 = 1/5.Perform multiplication: Step 2: Subtract the result from 2/5. Now, subtract 1/5 from 2/5. 2/5 - 1/5 = (2-1)/5 = 1/5.

______

Identify operations: Step $1$ : Identify the operations and order of operations in the expression. $\newline$ We need to solve $\frac{2}{5} - \frac{1}{4} \times \frac{4}{5}$ . According to the order of operations (PEMDAS/BODMAS), we first do the multiplication before subtraction. $\newline$ Calculation: First, multiply $\frac{1}{4}$ by $\frac{4}{5}$ . $\newline$ $\frac{1}{4} \times \frac{4}{5} = \frac{1\times4}{4\times5} = \frac{4}{20} = \frac{1}{5}$ .
Perform multiplication: Step $2$ : Subtract the result from $\frac{2}{5}$ . Now, subtract $\frac{1}{5}$ from $\frac{2}{5}$ . $\frac{2}{5} - \frac{1}{5} = \frac{(2-1)}{5} = \frac{1}{5}$ .
