this problem out all the way. X minus 33 1/3% equals 30.
First change the percent 33 1/3% to a fraction:
33 1/3% = (33 1/3)÷100 = (100/3)÷100 =
(100/3)÷(100/1) = (100/3)×(1/100) = 1/3
So
X - (33 1/3% of X) = 30
X - (1/3)X = 30
Multiply every term by 3
(3)X - (3)(1/3)X = (3)30
Simplify
3X - 1X = 90
Combine like terms
2X = 90
Divide both sides by 2
2X/2 = 90/2
X = 45
