Question

Add $1 half space and space 2 over 3$ .

$\frac{7}{6}$
$\frac{7}{3}$
$\frac{3}{5}$
$\frac{3}{2}$

hint Hint:

In this question we have to add two fractions for that we have to make denominator same this can be done by taking LCM. LCM is the least common multiple of two integers. We will use the prime factorization method to find the LCM. In prime factorization method the simply put the factor of each number and then for LCM we take product of factors by considering the repeated factors only one time with highest exponent.

The correct answer is: $7 over 6$

Step1: First we will write all the prime factors of the denominators
In this question the denominators are $2$ and $3$ .
Factors of $2$ are: $2 to the power of 1$
Factors of $3$ are: $3 to the power of 1$
Step2: For calculating the LCM we will multiply the factors by considering the common factors only one time with the highest exponent.
In this case there is no common factor so we will have to multiply all the factors
LCM ( $2$ , $3$ ) = $2 to the power of 1 cross times 3 to the power of 1$
LCM ( $2$ , $3$ ) = $6$
Step3: Now what we do is divide the LCM by each denominator and multiply the numerator by quotient and then add them
So, $6 over 2 equals 3$
and $6 over 3 equals 2$
So, we will multiply the numerator of $2$ by $3$ and numerator of $3$ by $2$ .
$fraction numerator 1 cross times 3 plus 2 cross times 2 over denominator 6 end fraction equals 7 over 6$
So, the sum of $1 half space and space 2 over 3$ is $7 over 6$ .
