Solve 1.25=2*9.9*10^-4*6.25/9*x

$$1.25= \frac{ 2 \times 9.9 \times { 10 }^{ -4 } \times 6.25 }{ 9 \times x }$$

Solve for x

$$x=0.0011$$

Steps for Solving Linear Equation

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 9x.

$$11.25x=2\times 9.9\times 10^{-4}\times 6.25$$

Multiply 2 and 9.9 to get 19.8.

$$11.25x=19.8\times 10^{-4}\times 6.25$$

Calculate 10 to the power of -4 and get \frac{1}{10000}.

$$11.25x=19.8\times \frac{1}{10000}\times 6.25$$

Multiply 19.8 and \frac{1}{10000} to get \frac{99}{50000}.

$$11.25x=\frac{99}{50000}\times 6.25$$

Multiply \frac{99}{50000} and 6.25 to get \frac{99}{8000}.

$$11.25x=\frac{99}{8000}$$

Divide both sides by 11.25.

$$x=\frac{\frac{99}{8000}}{11.25}$$

Express \frac{\frac{99}{8000}}{11.25} as a single fraction.

$$x=\frac{99}{8000\times 11.25}$$

Multiply 8000 and 11.25 to get 90000.

$$x=\frac{99}{90000}$$

Reduce the fraction \frac{99}{90000} to lowest terms by extracting and canceling out 9.

$$x=\frac{11}{10000}$$
