Step 4 :
Rewriting the whole as an Equivalent Fraction :
4.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 29 as the denominator :
17 17 • 29
17 = —— = ———————
1 29
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 :
4.2 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:
17 • 29 + 1 494
——————————— = ———
29 29
Equation at the end of step 4 :
494 1 1
(——— + ——) + —

Step 5 :
Calculating the Least Common Multiple :
5.1 Find the Least Common Multiple
The left denominator is : 29
The right denominator is : 48
| Prime Factor | Left Denominator | Right Denominator | L.C.M = Max {Left,Right} |
|---|---|---|---|
| 29 | 1 | 0 | 1 |
| 2 | 0 | 4 | 4 |
| 3 | 0 | 1 | 1 |
| Product of all Prime Factors | 29 | 48 | 1392 |
Least Common Multiple:
1392
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 = 48
Right_M = L.C.M / R_Deno = 29
Making Equivalent Fractions :
5.3 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. 494 • 48 —————————————————— = ———————— L.C.M 1392 R. Mult. • R. Num. 29 —————————————————— = ———— L.C.M 1392
Adding fractions that have a common denominator :
5.4 Adding up the two equivalent fractions
494 • 48 + 29 23741
————————————— = —————
1392 1392
Equation at the end of step 5 :
23741 1
————— + —
1392 8
Step 6 :
Calculating the Least Common Multiple :
6.1 Find the Least Common Multiple
The left denominator is : 1392
The right denominator is : 8
| Prime Factor | Left Denominator | Right Denominator | L.C.M = Max {Left,Right} |
|---|---|---|---|
| 2 | 4 | 3 | 4 |
| 3 | 1 | 0 | 1 |
| 29 | 1 | 0 | 1 |
| Product of all Prime Factors | 1392 | 8 | 1392 |
Least Common Multiple:
1392
Calculating Multipliers :
6.2 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 = 174
Making Equivalent Fractions :
6.3 Rewrite the two fractions into equivalent fractions
L. Mult. • L. Num. 23741 —————————————————— = ————— L.C.M 1392 R. Mult. • R. Num. 174 —————————————————— = ———— L.C.M 1392
Adding fractions that have a common denominator :
6.4 Adding up the two equivalent fractions
23741 + 174 23915
——————————— = —————
1392 1392
Final result :
23915
————— = 17.18032
1392
