Step 7 :
Calculating the Least Common Multiple :
7.1 Find the Least Common Multiple
The left denominator is : 16
The right denominator is : 229680
| Prime Factor | Left Denominator | Right Denominator | L.C.M = Max {Left,Right} |
|---|---|---|---|
| 2 | 4 | 4 | 4 |
| 3 | 0 | 2 | 2 |
| 5 | 0 | 1 | 1 |
| 11 | 0 | 1 | 1 |
| 29 | 0 | 1 | 1 |
| Product of all Prime Factors | 16 | 229680 | 229680 |
Least Common Multiple:
229680
Calculating Multipliers :
7.2 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 = 14355
Right_M = L.C.M / R_Deno = 1
Making Equivalent Fractions :
7.3 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. 3 • 14355 —————————————————— = ————————— L.C.M 229680 R. Mult. • R. Num. 13 —————————————————— = —————— L.C.M 229680
Adding fractions that have a common denominator :
7.4 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:
3 • 14355 + 13 21539
—————————————— = ——————
229680 114840
Final result :
21539
—————— = 0.18756
114840
