Given that, according to the rules of the order of operations, parentheses come first, we will first solve the exercise that appears within the parentheses.
We solve the multiplication exercise:
We divide the fraction (numerator by denominator)
And now the exercise obtained within the parentheses is
Finally, we divide:
Solve the following problem:
\( 187\times(8-5)= \)
The order of operations (PEMDAS) is a mathematical rule that ensures everyone gets the same answer! Parentheses always come first, so you must solve completely before dividing by 12.
Inside parentheses, you still follow PEMDAS! So solve multiplication and division from left to right: and , then subtract: .
Both and 2.4 are correct! In math, we often leave answers as improper fractions because they're exact. Decimals like 2.4 are also acceptable.
Without parentheses, you'd solve: from left to right for multiplication/division: . The parentheses completely change the order!
Substitute your result back into the original expression. Since , you should get . If it matches your answer, you're correct!
