Solve 5x/7=20/21

$$\frac{ 5x }{ 7 } = \frac{ 20 }{ 21 }$$

Solve for x

$$x = \frac{4}{3} = 1\frac{1}{3} \approx 1.333333333$$

Steps for Solving Linear Equation

Multiply both sides by 7.

$$5x=\frac{20}{21}\times 7$$

Express \frac{20}{21}\times 7 as a single fraction.

$$5x=\frac{20\times 7}{21}$$

Multiply 20 and 7 to get 140.

$$5x=\frac{140}{21}$$

Reduce the fraction \frac{140}{21} to lowest terms by extracting and canceling out 7.

$$5x=\frac{20}{3}$$

Divide both sides by 5.

$$x=\frac{\frac{20}{3}}{5}$$

Express \frac{\frac{20}{3}}{5} as a single fraction.

$$x=\frac{20}{3\times 5}$$

Multiply 3 and 5 to get 15.

$$x=\frac{20}{15}$$

Reduce the fraction \frac{20}{15} to lowest terms by extracting and canceling out 5.

$$x=\frac{4}{3}$$
