Evaluate the expression. 1/5 - 1/4 * 3/5 Write your answer as a fraction or as a whole or mixed number. ______

Identify operations order: Step 1: Identify the operations and their order in the expression. Expression: 1/5 - 1/4 * 3/5 According to the order of operations (PEMDAS/BODMAS), multiplication comes before subtraction.Perform multiplication: Step 2: Perform the multiplication part of the expression. Calculate 1/4 * 3/5. 1/4 * 3/5 = (1*3)/(4*5) = 3/20Subtract fractions: Step 3: Subtract the result from the first fraction. Subtract 3/20 from 1/5. 1/5 - 3/20 To subtract, find a common denominator. The common denominator for 5 and 20 is 20. 1/5 = 4/20 4/20 - 3/20 = 1/20

______

Identify operations order: Step $1$ : Identify the operations and their order in the expression. $\newline$ Expression: $\frac{1}{5} - \frac{1}{4} \times \frac{3}{5}$ $\newline$ According to the order of operations (PEMDAS/BODMAS), multiplication comes before subtraction.
Perform multiplication: Step $2$ : Perform the multiplication part of the expression. $\newline$ Calculate $\frac{1}{4} \times \frac{3}{5}$ . $\newline$ $\frac{1}{4} \times \frac{3}{5} = \frac{(1\times3)}{(4\times5)} = \frac{3}{20}$
Subtract fractions: Step $3$ : Subtract the result from the first fraction. $\newline$ Subtract $\frac{3}{20}$ from $\frac{1}{5}$ . $\newline$ $\frac{1}{5} - \frac{3}{20}$ $\newline$ To subtract, find a common denominator. The common denominator for $5$ and $20$ is $20$ . $\newline$ $\frac{1}{5} = \frac{4}{20}$ $\newline$ $\frac{4}{20} - \frac{3}{20} = \frac{1}{20}$
