Solve 0.7*0.2*0.25+0.3*0.8*0.25+0.3*0.2*0.75

$$0.7 \times 0.2 \times 0.25+0.3 \times 0.8 \times 0.25+0.3 \times 0.2 \times 0.75$$

Evaluate

$$0.14$$

Solution Steps

Multiply 0.7 and 0.2 to get 0.14.

$$0.14\times 0.25+0.3\times 0.8\times 0.25+0.3\times 0.2\times 0.75$$

Multiply 0.14 and 0.25 to get 0.035.

$$0.035+0.3\times 0.8\times 0.25+0.3\times 0.2\times 0.75$$

Multiply 0.3 and 0.8 to get 0.24.

$$0.035+0.24\times 0.25+0.3\times 0.2\times 0.75$$

Multiply 0.24 and 0.25 to get 0.06.

$$0.035+0.06+0.3\times 0.2\times 0.75$$

Add 0.035 and 0.06 to get 0.095.

$$0.095+0.3\times 0.2\times 0.75$$

Multiply 0.3 and 0.2 to get 0.06.

$$0.095+0.06\times 0.75$$

Multiply 0.06 and 0.75 to get 0.045.

$$0.095+0.045$$

Add 0.095 and 0.045 to get 0.14.

$$0.14$$

Factor

$$\frac{7}{2 \cdot 5 ^ {2}} = 0.14$$
