[ 1/1Inequality]
Assignment:Find the solution set of inequality 2%/(x+2%) <1.25% .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2 % / ( x + 2 % ) <1.25 % (1)
From the definition field of divisor
x + 2 % ≠ 0 (2 )
From inequality(1):
x < -0.02 或 x > 79/50
From inequality(2):
x < -1/50 或 x > -1/50
From inequalities (1) and (2)
x < -0.02 或 x > 79/50 (3)
The final solution set is :
x < -0.02 或 x > 79/50Your problem has not been solved here? Please take a look at the hot problems !
