Answer 2

To solve the given expression, let's break it down step by step:

1. Simplify the expression on the left side of the equation: -32/75 ÷ (48/55). - To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. - So, -32/75 ÷ (48/55) becomes -32/75 * (55/48). - Now, we can multiply the numerators and denominators: -32 * 55 / 75 * 48. - This simplifies to -1760 / 3600.

2. Simplify the expression on the right side of the equation: -1 + 1/14 ÷ 5 + 5/7. - First, let's simplify the division: 1/14 ÷ 5 becomes 1/14 * (1/5). - Now, we can multiply the numerators and denominators: 1 * 1 / 14 * 5. - This simplifies to 1/70. - Next, let's simplify the addition: -1 + 1/70 + 5/7. - To add fractions, we need a common denominator. The common denominator here is 70. - -1 can be written as -70/70, so the expression becomes -70/70 + 1/70 + 50/70. - Now, we can add the numerators: -70 + 1 + 50 = -19. - The final expression is -19/70.

3. Compare the two sides of the equation: -1760/3600 = -19/70. - To compare fractions, we can cross-multiply. - Cross-multiplying gives us -1760 * 70 = 3600 * -19. - Simplifying both sides of the equation gives us -123200 = -68400. - Since -123200 is not equal to -68400, the equation is not true.

Therefore, the given equation is not true.
