Answer 2

To solve the equation $-2 \frac{5}{8} \div x = 1 \frac{19}{20}$ for $x$, follow these steps:

Step 1: Convert the mixed numbers into improper fractions. $-2 \frac{5}{8} = -\frac{21}{8}$ $1 \frac{19}{20} = \frac{39}{20}$

Step 2: Rewrite the equation with the improper fractions. $-\frac{21}{8} \div x = \frac{39}{20}$

Step 3: Invert and multiply to solve for $x$. Multiply both sides of the equation by the reciprocal of $-\frac{21}{8}$, which is $-\frac{8}{21}$:

$x = \frac{39}{20} \times -\frac{8}{21}$

Step 4: Simplify the expression on the right side:

$x = \frac{39 \times -8}{20 \times 21}$

$x = -\frac{312}{420}$

Step 5: Reduce the fraction to its simplest form:

$x = -\frac{4}{5}$

So, the value of $x$ is $-\frac{4}{5}$.
