Solve 90*0.2+82*0.44+65*0.32+40*0.04

$$90 \times 0.2+82 \times 0.44+65 \times 0.32+40 \times 0.04$$

Evaluate

$$76.48$$

Solution Steps

Multiply 90 and 0.2 to get 18.

$$18+82\times 0.44+65\times 0.32+40\times 0.04$$

Multiply 82 and 0.44 to get 36.08.

$$18+36.08+65\times 0.32+40\times 0.04$$

Add 18 and 36.08 to get 54.08.

$$54.08+65\times 0.32+40\times 0.04$$

Multiply 65 and 0.32 to get 20.8.

$$54.08+20.8+40\times 0.04$$

Add 54.08 and 20.8 to get 74.88.

$$74.88+40\times 0.04$$

Multiply 40 and 0.04 to get 1.6.

$$74.88+1.6$$

Add 74.88 and 1.6 to get 76.48.

$$76.48$$

Factor

$$\frac{239 \cdot 2 ^ {3}}{5 ^ {2}} = 76\frac{12}{25} = 76.48$$
