Solve 2.23*0.66+(1.38+1.75)*2.23+(1.48+2.75)*2.23=

$$2.23 \times 0.66+(1.38+1.75) \times 2.23+(1.48+2.75) \times 2.23=$$

Evaluate

$$17.8846$$

Solution Steps

Multiply 2.23 and 0.66 to get 1.4718.

$$1.4718+\left(1.38+1.75\right)\times 2.23+\left(1.48+2.75\right)\times 2.23$$

Add 1.38 and 1.75 to get 3.13.

$$1.4718+3.13\times 2.23+\left(1.48+2.75\right)\times 2.23$$

Multiply 3.13 and 2.23 to get 6.9799.

$$1.4718+6.9799+\left(1.48+2.75\right)\times 2.23$$

Add 1.4718 and 6.9799 to get 8.4517.

$$8.4517+\left(1.48+2.75\right)\times 2.23$$

Add 1.48 and 2.75 to get 4.23.

$$8.4517+4.23\times 2.23$$

Multiply 4.23 and 2.23 to get 9.4329.

$$8.4517+9.4329$$

Add 8.4517 and 9.4329 to get 17.8846.

$$17.8846$$

Factor

$$\frac{223 \cdot 401}{2 ^ {3} \cdot 5 ^ {4}} = 17\frac{4423}{5000} = 17.8846$$
