Solve 391.6-21.5*(0.38+0.25)*0.6-51.38*3.45=

$$391.6-21.5 \times (0.38+0.25) \times 0.6-51.38 \times 3.45=$$

Evaluate

$$206.212$$

Solution Steps

Add 0.38 and 0.25 to get 0.63.

$$391.6-21.5\times 0.63\times 0.6-51.38\times 3.45$$

Multiply 21.5 and 0.63 to get 13.545.

$$391.6-13.545\times 0.6-51.38\times 3.45$$

Multiply 13.545 and 0.6 to get 8.127.

$$391.6-8.127-51.38\times 3.45$$

Subtract 8.127 from 391.6 to get 383.473.

$$383.473-51.38\times 3.45$$

Multiply 51.38 and 3.45 to get 177.261.

$$383.473-177.261$$

Subtract 177.261 from 383.473 to get 206.212.

$$206.212$$

Factor

$$\frac{31 \cdot 1663}{2 \cdot 5 ^ {3}} = 206\frac{53}{250} = 206.212$$
