Mathematical Expression Evaluation

To solve the given mathematical expression 7/12 * (-1/2) - 9/18 / (-3/4), we can follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, let's simplify the expression step by step:

1. 7/12 * (-1/2): - Multiply the fractions: (7 * -1) / (12 * 2) = -7/24

2. -9/18 / (-3/4): - Divide the fractions: (-9/18) / (-3/4) = (-9/18) * (-4/3) = 3/2

Now, we can combine the results:

-7/24 - 3/2

To subtract these fractions, we need to find a common denominator:

-7/24 = -14/48

Now, we can subtract:

-14/48 - 72/48 = -86/48

Simplifying the result:

-86/48 = -43/24

So, the value of the given expression 7/12 * (-1/2) - 9/18 / (-3/4) is -43/24.
