What is 1/8 plus 1/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/8
Fraction B: 1/10

What to be found?
1/8+1/10 = ?
Find what's the sum of 1/8 and 1/10.

step 2 Compare the denominators of fractions 1/8 and 1/10 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/8 and 1/10 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 1/8 and 1/10:
The LCM of 8 and 10 is 40.

step 4 Write the fractions 1/8 and 1/10 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/8+1/10
=(1 x 40)/(8 x 40)+(1 x 40)/(10 x 40)

step 5 Simplify the expression to have common denominator:
=5/40+4/40

step 6 Take the common values out and rewrite the above expression like the below:
=1/40 x (5/1+4/1)
=1/40 x (5 + 4)

step 7Simplify the above expression further:
=1/40 x 9
=9/40
1/8+1/10=9/40

Hence,
1/8 plus 1/10 equals to 9/40 in fraction.

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/8
Fraction B: 1/10

What to be found?
1/8+1/10 = ?
Find what's the sum of 1/8 and 1/10.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 10), find the product of numerator of Fraction B and denominator of Fraction A (1 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 10) and rewrite the equation as like the below:
= (1 x 10) + (1 x 8)/(8 x 10)

step 3 Simplify and rewrite the fraction:
= (10 + 8)/80
= 18/80
= 9/40
1/8+1/10 = 9/40
