7/9+2/4 using LCM Method:
What is 7/9 plus 2/4 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/9
Fraction B: 2/4
What to be found?
7/9+2/4 = ?
Find what's the sum of 7/9 and 2/4.
step 2 Compare the denominators of fractions 7/9 and 2/4 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/9 and 2/4 are not equal, it is said to be unlike fractions addition.
step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 7/9 and 2/4:
The LCM of 9 and 4 is 36.
step 4 Write the fractions 7/9 and 2/4 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/9+2/4
=(7 x 36)/(9 x 36)+(2 x 36)/(4 x 36)
step 5 Simplify the expression to have common denominator:
=28/36+18/36
step 6 Take the common values out and rewrite the above expression like the below:
=1/36 x (28/1+18/1)
=1/36 x (28 + 18)
step 7Simplify the above expression further:
=1/36 x 46
= 46/36
=23/18
7/9+2/4=23/18
Hence,

7/9+2/4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/9
Fraction B: 2/4
What to be found?
7/9+2/4 = ?
Find what's the sum of 7/9 and 2/4.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 4), find the product of numerator of Fraction B and denominator of Fraction A (2 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 4) and rewrite the equation as like the below:
= (7 x 4) + (2 x 9)/(9 x 4)
step 3 Simplify and rewrite the fraction:
= (28 + 18)/36
= 46/36
= 23/18
7/9+2/4 = 23/18
