Solve 0.55*2+0.71*2+0.57*7.5+0.58*2.5

$$0.55 \times 2 + 0.71 \times 2 + 0.57 \times 7.5 + 0.58 \times 2.5$$

Evaluate

$$8.245$$

Solution Steps

Multiply 0.55 and 2 to get 1.1.

$$1.1+0.71\times 2+0.57\times 7.5+0.58\times 2.5$$

Multiply 0.71 and 2 to get 1.42.

$$1.1+1.42+0.57\times 7.5+0.58\times 2.5$$

Add 1.1 and 1.42 to get 2.52.

$$2.52+0.57\times 7.5+0.58\times 2.5$$

Multiply 0.57 and 7.5 to get 4.275.

$$2.52+4.275+0.58\times 2.5$$

Add 2.52 and 4.275 to get 6.795.

$$6.795+0.58\times 2.5$$

Multiply 0.58 and 2.5 to get 1.45.

$$6.795+1.45$$

Add 6.795 and 1.45 to get 8.245.

$$8.245$$

Factor

$$\frac{17 \cdot 97}{2 ^ {3} \cdot 5 ^ {2}} = 8\frac{49}{200} = 8.245$$
