Question

(-1,25+17/8):(-11/12-0,5)=

Answer 1

$(-1,25 + \frac{17}{8}) :( -\frac{11}{12} -0,5) = (-1,25 + \frac{17}{8}) :(-\frac{11}{12} -0,5) = (-1,25+2,125) : (- \frac{11}{12} - \frac{1}{2})= \frac{7}{8} :(-1 \frac{5}{12})$  $=-( \frac{7*12}{8*17}) =- \frac{21}{34}$

Answer 2

To solve the given expression, follow the order of operations (PEMDAS/BODMAS):

P - Parentheses E - Exponents MD - Multiplication and Division (from left to right) AS - Addition and Subtraction (from left to right)

The given expression is:

(-1.25 + 17/8) / (-11/12 - 0.5)

Let's solve it step-by-step:

Step 1: Perform operations inside the parentheses: -1.25 + 17/8 = (-10/8 + 17/8) = (7/8)

Step 2: Rewrite the expression with the simplified value inside the parentheses: (7/8) / (-11/12 - 0.5)

Step 3: Perform the subtraction inside the parentheses: (-11/12 - 0.5) = (-11/12 - 6/12) = (-17/12)

Step 4: Rewrite the expression with the simplified value inside the parentheses: (7/8) / (-17/12)

Step 5: Now, divide the fractions: (7/8) ÷ (-17/12) = (7/8) * (-12/17)

Step 6: Multiply the fractions: (7/8) * (-12/17) = (7 * -12) / (8 * 17) = (-84) / 136

Step 7: Simplify the fraction, if possible: (-84) / 136 = -21 / 34

The final result is -21/34.
