Question

$$\frac{-5}{21}\times\frac{21}{-5}\times1$$

Evaluate

$1$

Solution Steps

Fraction $\frac{-5}{21}$ can be rewritten as $-\frac{5}{21}$ by extracting the negative sign.

$$-\frac{5}{21}\times \frac{21}{-5}$$

Fraction $\frac{21}{-5}$ can be rewritten as $-\frac{21}{5}$ by extracting the negative sign.

$$-\frac{5}{21}\left(-\frac{21}{5}\right)$$

Multiply $-\frac{5}{21}$ times $-\frac{21}{5}$ by multiplying numerator times numerator and denominator times denominator.

$$\frac{-5\left(-21\right)}{21\times 5}\times 1$$

Do the multiplications in the fraction $\frac{-5\left(-21\right)}{21\times 5}$.

$$\frac{105}{105}\times 1$$

Divide $105$ by $105$ to get $1$.

$$1\times 1$$

Multiply $1$ and $1$ to get $1$.

$$1$$

Factor

$1$
