Solve (1.3*7+12+10+3.7*6+3.3*6)div30=

$$(1.3 \times 7+12+10+3.7 \times 6+3.3 \times 6) \div 30=$$

Evaluate

$$\frac{731}{300}\approx 2.436666667$$

Solution Steps

Multiply 1.3 and 7 to get 9.1.

$$\frac{9.1+12+10+3.7\times 6+3.3\times 6}{30}$$

Add 9.1 and 12 to get 21.1.

$$\frac{21.1+10+3.7\times 6+3.3\times 6}{30}$$

Add 21.1 and 10 to get 31.1.

$$\frac{31.1+3.7\times 6+3.3\times 6}{30}$$

Multiply 3.7 and 6 to get 22.2.

$$\frac{31.1+22.2+3.3\times 6}{30}$$

Add 31.1 and 22.2 to get 53.3.

$$\frac{53.3+3.3\times 6}{30}$$

Multiply 3.3 and 6 to get 19.8.

$$\frac{53.3+19.8}{30}$$

Add 53.3 and 19.8 to get 73.1.

$$\frac{73.1}{30}$$

Expand \frac{73.1}{30} by multiplying both numerator and the denominator by 10.

$$\frac{731}{300}$$

Factor

$$\frac{17 \cdot 43}{3 \cdot 2 ^ {2} \cdot 5 ^ {2}} = 2\frac{131}{300} = 2.4366666666666665$$
