Step by Step Solution
Rearrange:Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 1/3-(x/100)=0
Step by step solution :
Step 1 :
x Simplify ——— 100Equation at the end of step 1 : 1 x — - ——— = 0 3 100
Step 2 :1 Simplify — 3Equation at the end of step 2 : 1 x — - ——— = 0 3 100
Step 3 :Calculating the Least Common Multiple :3.1 Find the Least Common Multiple The left denominator is : 3 The right denominator is : 100
|Product of allPrime Factors||3||100||300|
Least Common Multiple: 300Calculating Multipliers :
3.2 Calculate multipliers for the two fractions Denote the Least Common Multiple by L.C.M Denote the Left Multiplier by Left_M Denote the Right Multiplier by Right_M Denote the Left Deniminator by L_Deno Denote the Right Multiplier by R_DenoLeft_M=L.C.M/L_Deno=100Right_M=L.C.M/R_Deno=3Making Equivalent Fractions :
3.3 Rewrite the two fractions into equivalent fractionsTwo fractions are called equivalent if they have the same numeric value. For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well. To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

Num. x • 3 —————————————————— = ————— L.C.M 300 Adding fractions that have a common denominator :3.4 Adding up the two equivalent fractions Add the two equivalent fractions which now have a common denominatorCombine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
100 - (x • 3) 100 - 3x ————————————— = ———————— 300 300 Equation at the end of step 3 : 100 - 3x ———————— = 0 300
Step 4 :When a fraction equals zero :4.1 When a fraction equals zero ...Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.Here"s how:
100-3x —————— • 300 = 0 • 300 300 Now, on the left hand side, the 300 cancels out the denominator, while, on the right hand side, zero times anything is still zero.The equation now takes the shape:100-3x=0
Solving a Single Variable Equation:4.2Solve:-3x+100 = 0Subtract 100 from both sides of the equation:-3x = -100 Multiply both sides of the equation by (-1) : 3x = 100 Divide both sides of the equation by 3:x = 100/3 = 33.333
