Calculating the Least Common Multiple :
4.1 Find the Least Common Multiple
The left denominator is : 50
The right denominator is : 1000
| Prime Factor | Left Denominator | Right Denominator | L.C.M = Max {Left,Right} |
|---|---|---|---|
| 2 | 1 | 3 | 3 |
| 5 | 2 | 3 | 3 |
| Product of all Prime Factors | 50 | 1000 | 1000 |
Least Common Multiple:
1000
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 = 20
Right_M = L.C.M / R_Deno = 1
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. 243 • 20 —————————————————— = ———————— L.C.M 1000 R. Mult. • R. Num. 29 —————————————————— = ———— L.C.M 1000
Adding fractions that have a common denominator :
4.4 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:
243 • 20 + 29 4889
————————————— = ————
1000 1000
Equation at the end of step 4 :
4889 117
———— + ———
1000 10
Step 5 :
Calculating the Least Common Multiple :
5.1 Find the Least Common Multiple
The left denominator is : 1000
The right denominator is : 10
| Prime Factor | Left Denominator | Right Denominator | L.C.M = Max {Left,Right} |
|---|---|---|---|
| 2 | 3 | 1 | 3 |
| 5 | 3 | 1 | 3 |
| Product of all Prime Factors | 1000 | 10 | 1000 |
Least Common Multiple:
1000
Calculating Multipliers :
5.2 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 = 1
Right_M = L.C.M / R_Deno = 100
Making Equivalent Fractions :
5.3 Rewrite the two fractions into equivalent fractions
L. Mult. • L. Num. 4889 —————————————————— = ———— L.C.M 1000 R. Mult. • R. Num. 117 • 100 —————————————————— = ————————— L.C.M 1000
Adding fractions that have a common denominator :
5.4 Adding up the two equivalent fractions
4889 + 117 • 100 16589
———————————————— = —————
1000 1000
Final result :
16589
————— = 16.58900
