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} to lowest terms by extracting and canceling out 160.
