Solution - Adding, subtracting and finding the least common multiple
Step by Step Solution
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
5-3/2*x-(1/3)>0
Step by step solution :
Step 1 :

Step 3 :
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 2 as the denominator :
5 5 • 2
5 = — = —————
1 2
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
5 • 2 - (3x) 10 - 3x
———————————— = ———————
2 2
Equation at the end of step 3 :
(10 - 3x) 1
————————— - — > 0

Step 4 :
Calculating the Least Common Multiple :
4.1 Find the Least Common Multiple
The left denominator is : 2
The right denominator is : 3
Prime Factor | Left Denominator | Right Denominator | L.C.M = Max {Left,Right} |
---|---|---|---|
2 | 1 | 0 | 1 |
3 | 0 | 1 | 1 |
Product of all Prime Factors | 2 | 3 | 6 |
Least Common Multiple:
6
Calculating Multipliers :
4.2 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_Deno
Left_M = L.C.M / L_Deno = 3
Right_M = L.C.M / R_Deno = 2
Making Equivalent Fractions :
4.3 Rewrite the two fractions into equivalent fractions
Two 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.
L. Mult. • L. Num. (10-3x) • 3 —————————————————— = ——————————— L.C.M 6 R. Mult. • R. Num. 2 —————————————————— = — L.C.M 6
Adding fractions that have a common denominator :
4.4 Adding up the two equivalent fractions
(10-3x) • 3 - (2) 28 - 9x
————————————————— = ———————
6 6
Equation at the end of step 4 :
28 - 9x
——————— > 0
6
Step 5 :
5.1 Multiply both sides by 6
5.2 Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
9x-28 < 0
5.3 Divide both sides by 9
x-(28/9) < 0
Solve Basic Inequality :
5.4 Add 28/9 to both sides
x < 28/9
