x\times 760=390\times 800
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 390x, the least common multiple of 390,x.
x\times 760=312000
Multiply 390 and 800 to get 312000.
x=\frac{312000}{760}
Divide both sides by 760.
x=\frac{7800}{19}
Reduce the fraction \frac{312000}{760} to lowest terms by extracting and canceling out 40.
