Calculating the Least Common Multiple :
3.1 Find the Least Common Multiple

The left denominator is : 5

The right denominator is : 2

Number of times each prime factor
appears in the factorization of:
Prime
Factor Left
Denominator Right
Denominator L. C.M = Max
{Left, Right}
5 1 0 1
2 0 1 1
Product of all
Prime Factors 5 2 10

Least Common Multiple:
10

Calculating 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_Deno

Left_M = L. C.M / L_Deno = 2

Right_M = L. C.M / R_Deno = 5

Making Equivalent Fractions :
3.3 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. -13 • 2
—————————————————— = ———————
L. C.M 10

R. Mult. • R. Num. -7 • 5
—————————————————— = ——————
L. C.M 10
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 denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-13 • 2 + -7 • 5 -61
———————————————— = ———
10 10
Final result :
-61
——— = -6.10000
