What is 1/9 plus 1/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/9
Fraction B: 1/10

What to be found?
1/9+1/10 = ?
Find what's the sum of 1/9 and 1/10.

step 2 Compare the denominators of fractions 1/9 and 1/10 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/9 and 1/10 are not equal, it is said to be unlike fractions addition.

The LCM of 9 and 10 is 90.

step 4 Write the fractions 1/9 and 1/10 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/9+1/10
=(1 x 90)/(9 x 90)+(1 x 90)/(10 x 90)

step 5 Simplify the expression to have common denominator:
=10/90+9/90

step 6 Take the common values out and rewrite the above expression like the below:
=1/90 x (10/1+9/1)
=1/90 x (10 + 9)

step 7Simplify the above expression further:
=1/90 x 19
=19/90
1/9+1/10=19/90

Hence,
