Evaluate

\frac{18 \times 42}{140} = \frac{30 x}{100}

Reduce the fraction

More Steps

\frac{27}{5} = \frac{30 x}{100}

Cancel out the common factor 10

\frac{27}{5} = \frac{3 x}{10}

Swap the sides of the equation

\frac{3 x}{10} = \frac{27}{5}

Multiply both sides of the equation by 10

\frac{3 x}{10} \times 10 = \frac{27}{5} \times 10

Multiply the terms

3 x = \frac{27 \times 10}{5}

Divide the terms

3 x = 54

Divide both sides

\frac{3 x}{3} = \frac{54}{3}

Divide the numbers

x = \frac{54}{3}
