Solve (1.5*10^7-3*10^6)*0.03/3.9*10^7

$$\frac { ( 1.5 \times 10 ^ { 7 } - 3 \times 10 ^ { 6 } ) \times 0.03 } { 3.9 \times 10 ^ { 7 } }$$

Evaluate

$$\frac{3}{325}\approx 0.009230769$$

Solution Steps

Calculate 10 to the power of 7 and get 10000000.

$$\frac{\left(1.5\times 10000000-3\times 10^{6}\right)\times 0.03}{3.9\times 10^{7}}$$

Multiply 1.5 and 10000000 to get 15000000.

$$\frac{\left(15000000-3\times 10^{6}\right)\times 0.03}{3.9\times 10^{7}}$$

Calculate 10 to the power of 6 and get 1000000.

$$\frac{\left(15000000-3\times 1000000\right)\times 0.03}{3.9\times 10^{7}}$$

Multiply 3 and 1000000 to get 3000000.

$$\frac{\left(15000000-3000000\right)\times 0.03}{3.9\times 10^{7}}$$

Subtract 3000000 from 15000000 to get 12000000.

$$\frac{12000000\times 0.03}{3.9\times 10^{7}}$$

Multiply 12000000 and 0.03 to get 360000.

$$\frac{360000}{3.9\times 10^{7}}$$

Calculate 10 to the power of 7 and get 10000000.

$$\frac{360000}{3.9\times 10000000}$$

Multiply 3.9 and 10000000 to get 39000000.

$$\frac{360000}{39000000}$$

Reduce the fraction \frac{360000}{39000000} to lowest terms by extracting and canceling out 120000.

$$\frac{3}{325}$$

Factor

$$\frac{3}{13 \cdot 5 ^ {2}} = 0.009230769230769232$$
