\frac{4}{5}\times \frac{1}{2}\times 30x=\frac{2}{3}\times 30\times 3
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 30x, the least common multiple of 5,2,3,x.
\frac{4\times 1}{5\times 2}\times 30x=\frac{2}{3}\times 30\times 3
Multiply \frac{4}{5} times \frac{1}{2} by multiplying numerator times numerator and denominator times denominator.
\frac{4}{10}\times 30x=\frac{2}{3}\times 30\times 3
Do the multiplications in the fraction \frac{4\times 1}{5\times 2}.
\frac{2}{5}\times 30x=\frac{2}{3}\times 30\times 3
Reduce the fraction \frac{4}{10} to lowest terms by extracting and canceling out 2.
\frac{2\times 30}{5}x=\frac{2}{3}\times 30\times 3
Express \frac{2}{5}\times 30 as a single fraction.
\frac{60}{5}x=\frac{2}{3}\times 30\times 3
Multiply 2 and 30 to get 60.
12x=\frac{2}{3}\times 30\times 3
Divide 60 by 5 to get 12.
12x=\frac{2\times 30}{3}\times 3
Express \frac{2}{3}\times 30 as a single fraction.
12x=\frac{60}{3}\times 3
Multiply 2 and 30 to get 60.
12x=20\times 3
Divide 60 by 3 to get 20.
12x=60
Multiply 20 and 3 to get 60.
x=\frac{60}{12}
Divide both sides by 12.
x=5
Divide 60 by 12 to get 5.
