(80)/x = 40/100

\frac{80}{x} = \frac{40}{100}

x = 200

Solution steps

\frac{80}{x} = \frac{40}{100}

Cross multiply

8000 = x \cdot 40

Switch sides

x \cdot 40 = 8000

Divide both sides by

40

x = 200

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 200

1 + 0.1 = (1 - d)^{- 1}

10.5 = \frac{2500}{x}

0 = \frac{3}{6 x + 2}

2 x^{- 3} = \frac{1}{2 x ^{3}}

\frac{4 x}{3 - 6 x} = 1 - x
