Solution Steps

Multiply -4.47 and 0.4 to get -1.788.

$$-1.788-12.57\left(-1.52\right)+5.34\left(-1.29\right)-0.63\left(-1.13\right)$$

Multiply 12.57 and -1.52 to get -19.1064.

$$-1.788-\left(-19.1064\right)+5.34\left(-1.29\right)-0.63\left(-1.13\right)$$

The opposite of -19.1064 is 19.1064.

$$-1.788+19.1064+5.34\left(-1.29\right)-0.63\left(-1.13\right)$$

Add -1.788 and 19.1064 to get 17.3184.

$$17.3184+5.34\left(-1.29\right)-0.63\left(-1.13\right)$$

Multiply 5.34 and -1.29 to get -6.8886.

$$17.3184-6.8886-0.63\left(-1.13\right)$$

Subtract 6.8886 from 17.3184 to get 10.4298.

$$10.4298-0.63\left(-1.13\right)$$

Multiply 0.63 and -1.13 to get -0.7119.

$$10.4298-\left(-0.7119\right)$$

The opposite of -0.7119 is 0.7119.

$$10.4298+0.7119$$

Add 10.4298 and 0.7119 to get 11.1417.

$$11.1417$$

Factor

$$\frac{3 \cdot 37139}{2 ^ {4} \cdot 5 ^ {4}} = 11\frac{1417}{10000} = 11.1417$$
