To solve the expression , we need to follow the order of operations, commonly known by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). In this question, we focus on Parentheses and Addition.
Step-by-Step Solution:
Therefore, the final answer is .
Solve the following problem:
\( 187\times(8-5)= \)
Because the parentheses tell you to add first! The expression means 9 divided by the entire sum of 42 + 7, not 9/42 plus something else.
Check if 9 and 49 share any common factors. Since 9 = 3×3 and 49 = 7×7, they don't share any factors except 1, so is already in simplest form.
Double-check your addition! . If you got a different sum like 48 or 50, you'd get the wrong final answer. Always verify your arithmetic step by step.
Not really! Order of operations exists for a reason. You must do the addition in parentheses first. Trying shortcuts will lead to wrong answers every time.
No, because 9 < 49. Since the numerator is smaller than the denominator, is a proper fraction less than 1 and cannot be written as a mixed number.
