x\times 320=400\times 10

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 400x, the least common multiple of 400,x.

x\times 320=4000

Multiply 400 and 10 to get 4000.

x=\frac{4000}{320}

Divide both sides by 320.

x=\frac{25}{2}

Reduce the fraction \frac{4000}{320}=12.5 to lowest terms by extracting and canceling out 160.
