-5/8y =25/16

1 answer

To solve the equation \(-\frac{5}{8}y = \frac{25}{16}\), follow these steps:

  1. Isolate \(y\): First, we can get \(y\) by multiplying both sides of the equation by the reciprocal of \(-\frac{5}{8}\).

    The reciprocal of \(-\frac{5}{8}\) is \(-\frac{8}{5}\).

    \[ y = \frac{25}{16} \cdot -\frac{8}{5} \]

  2. Multiply the fractions:

    \[ y = \frac{25 \cdot -8}{16 \cdot 5} \]

    Calculating the numerator and the denominator:

    \[ y = \frac{-200}{80} \]

  3. Simplify the fraction:

    Dividing both the numerator and the denominator by 40:

    \[ y = \frac{-5}{2} \]

Thus, the solution to the equation \(-\frac{5}{8}y = \frac{25}{16}\) is:

\[ y = -\frac{5}{2} \]
