Solve 0.4*0.5*0.3+0.6*0.5*0.3+0.6*0.5*0.7

$$0.4 \times 0.5 \times 0.3+0.6 \times 0.5 \times 0.3+0.6 \times 0.5 \times 0.7$$

Evaluate

$$0.36$$

Solution Steps

Multiply 0.4 and 0.5 to get 0.2.

$$0.2\times 0.3+0.6\times 0.5\times 0.3+0.6\times 0.5\times 0.7$$

Multiply 0.2 and 0.3 to get 0.06.

$$0.06+0.6\times 0.5\times 0.3+0.6\times 0.5\times 0.7$$

Multiply 0.6 and 0.5 to get 0.3.

$$0.06+0.3\times 0.3+0.6\times 0.5\times 0.7$$

Multiply 0.3 and 0.3 to get 0.09.

$$0.06+0.09+0.6\times 0.5\times 0.7$$

Add 0.06 and 0.09 to get 0.15.

$$0.15+0.6\times 0.5\times 0.7$$

Multiply 0.6 and 0.5 to get 0.3.

$$0.15+0.3\times 0.7$$

Multiply 0.3 and 0.7 to get 0.21.

$$0.15+0.21$$

Add 0.15 and 0.21 to get 0.36.

$$0.36$$

Factor

$$\frac{3 ^ {2}}{5 ^ {2}} = 0.36$$
