Question - Solving an Equation Using PEMDAS Order of Operations
Solution:
To solve the equation in the image, follow the order of operations, commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). Division and multiplication are done from left to right, as are addition and subtraction.The equation is: 9 - 3 ÷ (1/3) + 1.Now, let's solve it step by step:1. First, perform the division: 3 ÷ (1/3). Since dividing by a fraction is the same as multiplying by its reciprocal, this becomes 3 * (3/1), which equals 9.2. Now, replace the division part with the result, 9: 9 - 9 + 1.3. Then, perform the subtraction: 9 - 9 equals 0.4. Finally, perform the addition: 0 + 1 equals 1.So, the answer to the equation is 1.
