25/20 or 1 and 1/4
The LCD is 30.
Assume an additive expression.X5 + X3X3(X2 + 1)--------------------so,X3====Is the LCD
25/20 = 5/4 = 5 and 1/4 = 5.25
5100. If that's 2/5, 1/2 and 3/4, the LCD is 20.
Reduce the common factors in the numerator and denominator to get: 25 / 500 = 25 / (25 * 20) = 1 / 20

no, 1/5 is .20 and 1/4 is .25
