Math Problem Statement

Divide and simplify the expression: 4/5 ÷ (-11/2).

Solution

The problem shown in the image asks to divide and simplify the following expression:

45÷(112)\frac{4}{5} \div \left( \frac{-11}{2} \right)

Step-by-Step Solution:

  1. Division of Fractions Rule: Dividing by a fraction is the same as multiplying by its reciprocal. So the expression becomes: 45×(211)\frac{4}{5} \times \left( \frac{-2}{11} \right) This is because the reciprocal of 112\frac{-11}{2} is 211\frac{-2}{11}.

  2. Multiplying Fractions: Now, multiply the numerators and denominators: 4×25×11=855\frac{4 \times -2}{5 \times 11} = \frac{-8}{55}

Thus, the simplified result of the division is: 855\frac{-8}{55}
