Learn how to find what is 4/9 plus 1/15 in fraction form just in a few minutes. We have covered the easiest method to write 4/9 + 1/15 as a fraction and decimal.
Summary: 4/9 plus 1/15 = 23/45
Since both fractions have unequal denominators, 4/9 plus 1/15 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 4/9 and fraction 1/15 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 9 and 15. 45 is the LCM of 9 and 15. Multiplying the LCM 45 with the numerators and denominators of both fractions (4/9 x 45/45) + (1/15 x 45/45), and simplify further in order to have the common denominator. So the equivalent fraction for 4/9 is 20/45 and for 1/15 is 3/45. By simplifying this fraction addition 20/45 + 3/45, it becomes 23/45.
Pie Chart Representation: 4/9 + 1/15 = 23/45
The below workout with step by step calculation shows how to find the equivalent fraction between 4/9 and 1/15 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 4/9 plus 1/15 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
(4/9) + (1/15) using LCM Method:
What is 4/9 plus 1/15 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/9
Fraction B: 1/15
What to be found?
(4/9) + (1/15) = ?
Find what's the sum of 4/9 and 1/15.
step 2 Compare the denominators of fractions 4/9 and 1/15 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 4/9 and 1/15 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 4/9 and 1/15:
The LCM of 9 and 15 is 45.
step 4 Write the fractions 4/9 and 1/15 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 4/9 + 1/15
= [(4 x 45)/(9 x 45)] + [(1 x 45)/(15 x 45)]
step 5 Simplify the expression to have common denominator:
= 20/45 + 3/45
step 6 Take the common values out and rewrite the above expression like the below:
= 1/45 x (20/1 + 3/1)
= 1/45 x (20 + 3)
step 7Simplify the above expression further:
= 1/45 x 23
= 23/45
4/9 + 1/15 = 23/45
Hence,
4/9 plus 1/15 as a fraction is 23/45.
4/9 + 1/15 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/9
Fraction B: 1/15
What to be found?
(4/9)+(1/15) = ?
Find what's the sum of 4/9 and 1/15.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (4 x 15), find the product of numerator of Fraction B and denominator of Fraction A (1 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 15) and rewrite the equation as like the below:
= (4 x 15) + (1 x 9)/(9 x 15)
step 3 Simplify and rewrite the fraction:
= (60 + 9)/135
= 69/135
= 23/45
4/9 + 1/15 = 23/45
Hence,
4/9 plus 1/15 in fraction is 23/45
