Solve K=21/-8*-22/15

$$K = \frac { 21 } { - 8 } \times \frac { - 22 } { 15 }$$

Solve for K

$$K = \frac{77}{20} = 3\frac{17}{20} = 3.85$$

Steps for Solving Linear Equation

Fraction \frac{21}{-8} can be rewritten as -\frac{21}{8} by extracting the negative sign.

$$K=-\frac{21}{8}\times \frac{-22}{15}$$

Fraction \frac{-22}{15} can be rewritten as -\frac{22}{15} by extracting the negative sign.

$$K=-\frac{21}{8}\left(-\frac{22}{15}\right)$$

Multiply -\frac{21}{8} times -\frac{22}{15} by multiplying numerator times numerator and denominator times denominator.

$$K=\frac{-21\left(-22\right)}{8\times 15}$$

Do the multiplications in the fraction \frac{-21\left(-22\right)}{8\times 15}.

$$K=\frac{462}{120}$$

Reduce the fraction \frac{462}{120} to lowest terms by extracting and canceling out 6.

$$K=\frac{77}{20}$$

Assign K

$$K≔\frac{77}{20}$$
