I explain to you detailed this exercise:
To realize this operation, we must extract the "Common Multiple Minimum" to the numbers 3 and 6 respectively of the following way:
3.6!3
1.2!2
1.1
Now we multiply the results:
2 x 3 = 6
The C.M.M is 6.
Now the result of the C.C.M divides for every fraction in the denominator and then it multiplies for the numerator of the same fraction, this way:
With the fraction 2x/3:
6 ÷ 3 = 2 x 2x =4x
With the fraction 1x/6:
6 ÷ 6 = 1 x 1x = 1x
Now we return to the exercise, but with the new numerator that 6:
4x + 1x / 6 = 2
We add the numerators:
5x/6 = 2
Now 6 that it is dividing it happens to it multiplies with 2 and clearing 5 dividing to another side of the equation, this way:
x=2 x 6/5
We solve the exercise:
X=12/5
The result is a 12/5, twelve fifth ones!
CHECKING:
2/3 (12/5) + 1/6 (12/5) = 2
24/15 + 12/30 = 2
48+12/30 = 2
60/30 = 2
2 = 2
Already we verify that this it is the result, I hope that they serve you. Happy night and good-bye
