Me and my mom are having an agrument about how to solve this problem.
27 / (5+4) * 19=
she says the answer is 57 and I say the answer is 6 with a remainder of 9..can you please tell me who is right. Thank you.
27 / (5+4) * 19 = 27 / (9) * 19=3*19=57. Mom is right.
i assume it is read like this:
[27/(5+4)] * 19 which is
(27/9) * 19 <=> 3*19 = 57
The rules of prioity are:
1. Parentheses
2. exponents
3. multiplications and divisions, from left to right
4. additions and subtractions, from left to right.
For 27 / (5+4) * 19=
you would first tackle the parentheses to get
27/9*19
Then multiplications and divisions from left to right to get
3*19=57
as was correctly evaluated by the previous posters and by your mom.
To solve the expression 27 / (5+4) * 19, we follow the order of operations, which is commonly remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, and Addition and Subtraction - from left to right). Let's break down the step-by-step process:
1. Begin by performing the operation inside the parentheses: 5 + 4 = 9.
So now the expression becomes: 27 / 9 * 19.
2. Next, solve the division operation: 27 / 9 = 3.
The expression becomes: 3 * 19.
3. Lastly, perform the multiplication operation: 3 * 19 = 57.
Therefore, the correct answer is 57. Your mom is right.
If you were aiming to solve the expression with a remainder, you would need to use a different mathematical operation, called "modulo" or "remainder division." However, based on the given expression, no remainder division operation is needed or mentioned.
