Solve (0.6+0.9+2+3.3+1.2*4+1.3*5+1.4*3+9.7)1/20

$$(0.6+0.9+2+3.3+1.2 \times 4+1.3 \times 5+1.4 \times 3+9.7) \frac{ 1 }{ 20 }$$

Evaluate

$$1.6$$

Solution Steps

Add 0.6 and 0.9 to get 1.5.

$$\left(1.5+2+3.3+1.2\times 4+1.3\times 5+1.4\times 3+9.7\right)\times \frac{1}{20}$$

Add 1.5 and 2 to get 3.5.

$$\left(3.5+3.3+1.2\times 4+1.3\times 5+1.4\times 3+9.7\right)\times \frac{1}{20}$$

Add 3.5 and 3.3 to get 6.8.

$$\left(6.8+1.2\times 4+1.3\times 5+1.4\times 3+9.7\right)\times \frac{1}{20}$$

Multiply 1.2 and 4 to get 4.8.

$$\left(6.8+4.8+1.3\times 5+1.4\times 3+9.7\right)\times \frac{1}{20}$$

Add 6.8 and 4.8 to get 11.6.

$$\left(11.6+1.3\times 5+1.4\times 3+9.7\right)\times \frac{1}{20}$$

Multiply 1.3 and 5 to get 6.5.

$$\left(11.6+6.5+1.4\times 3+9.7\right)\times \frac{1}{20}$$

Add 11.6 and 6.5 to get 18.1.

$$\left(18.1+1.4\times 3+9.7\right)\times \frac{1}{20}$$

Multiply 1.4 and 3 to get 4.2.

$$\left(18.1+4.2+9.7\right)\times \frac{1}{20}$$

Add 18.1 and 4.2 to get 22.3.

$$\left(22.3+9.7\right)\times \frac{1}{20}$$

Add 22.3 and 9.7 to get 32.

$$32\times \frac{1}{20}$$

Multiply 32 and \frac{1}{20} to get \frac{32}{20}.

$$\frac{32}{20}$$

Reduce the fraction \frac{32}{20} to lowest terms by extracting and canceling out 4.

$$\frac{8}{5}$$

Factor

$$\frac{2 ^ {3}}{5} = 1\frac{3}{5} = 1.6$$
