Solution Steps

Cancel out 2\times 5 in both numerator and denominator.

$$\frac{-2,1\times 0,25}{-0,5\times 0,01\times 5\times 21}$$

Multiply -2,1 and 0,25 to get -0,525.

$$\frac{-0,525}{-0,5\times 0,01\times 5\times 21}$$

Multiply -0,5 and 0,01 to get -0,005.

$$\frac{-0,525}{-0,005\times 5\times 21}$$

Multiply -0,005 and 5 to get -0,025.

$$\frac{-0,525}{-0,025\times 21}$$

Multiply -0,025 and 21 to get -0,525.

$$\frac{-0,525}{-0,525}$$
