Multiply the LCM 90 with all the numerators and denominators of both fractions (2/9 x 90/90) + (2/10 x 90/90) and simplify further in order to have the common denominators. By simplifying the fraction addition expression becomes 38/90.
The below workout with step by step calculation shows how to find the equivalent fraction between 2/9 and 2/10 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 2/9 plus 2/10 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
2/9+2/10 using LCM Method:
What is 2/9 plus 2/10 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/9
Fraction B: 2/10
What to be found?
2/9+2/10 = ?
Find what's the sum of 2/9 and 2/10.
step 2 Compare the denominators of fractions 2/9 and 2/10 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 2/9 and 2/10 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 2/9 and 2/10:
The LCM of 9 and 10 is 90.
step 4 Write the fractions 2/9 and 2/10 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=2/9+2/10
=(2 x 90)/(9 x 90)+(2 x 90)/(10 x 90)
step 5 Simplify the expression to have common denominator:
=20/90+18/90
step 6 Take the common values out and rewrite the above expression like the below:
=1/90 x (20/1+18/1)
=1/90 x (20 + 18)
step 7Simplify the above expression further:
=1/90 x 38
= 38/90
=19/45
2/9+2/10=19/45
Hence,
2/9 plus 2/10 equals to 19/45 in fraction.
2/9+2/10 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/9
Fraction B: 2/10
What to be found?
2/9+2/10 = ?
Find what's the sum of 2/9 and 2/10.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 10), 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 10) and rewrite the equation as like the below:
= (2 x 10) + (2 x 9)/(9 x 10)
step 3 Simplify and rewrite the fraction:
= (20 + 18)/90
= 38/90
= 19/45
2/9+2/10 = 19/45
Hence,
2/9 plus 2/10 = 19/45
