Solve 525*90+70/2-20/frac{95+75{2}-18}*10^-6=

$$525 \times \frac{ \frac{ 90+70 }{ 2 } -20 }{ \frac{ 95+75 }{ 2 } -18 } \times { 10 }^{ -6 } =$$

Evaluate

$$\frac{63}{134000}\approx 0.000470149$$

Solution Steps

Add 90 and 70 to get 160.

$$525\times \frac{\frac{160}{2}-20}{\frac{95+75}{2}-18}\times 10^{-6}$$

Divide 160 by 2 to get 80.

$$525\times \frac{80-20}{\frac{95+75}{2}-18}\times 10^{-6}$$

Subtract 20 from 80 to get 60.

$$525\times \frac{60}{\frac{95+75}{2}-18}\times 10^{-6}$$

Add 95 and 75 to get 170.

$$525\times \frac{60}{\frac{170}{2}-18}\times 10^{-6}$$

Divide 170 by 2 to get 85.

$$525\times \frac{60}{85-18}\times 10^{-6}$$

Subtract 18 from 85 to get 67.

$$525\times \frac{60}{67}\times 10^{-6}$$

Multiply 525 and \frac{60}{67} to get \frac{31500}{67}.

$$\frac{31500}{67}\times 10^{-6}$$

Calculate 10 to the power of -6 and get \frac{1}{1000000}.

$$\frac{31500}{67}\times \frac{1}{1000000}$$

Multiply \frac{31500}{67} and \frac{1}{1000000} to get \frac{63}{134000}.

$$\frac{63}{134000}$$

Factor

$$\frac{3 ^ {2} \cdot 7}{2 ^ {4} \cdot 5 ^ {3} \cdot 67} = 0.0004701492537313433$$
