What is 7/8 plus 8 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/8
Fraction B: 8/1

What to be found?
7/8+8 = ?
Find what's the sum of 7/8 and 8.

step 2 Compare the denominators of fractions 7/8 and 8 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/8 and 8 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 7/8 and 8:
The LCM of 8 and 1 is 8.

step 4 Write the fractions 7/8 and 8 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/8+8
=(7 x 8)/(8 x 8)+(8 x 8)/(1 x 8)

step 5 Simplify the expression to have common denominator:
=7/8+64/8

step 6 Take the common values out and rewrite the above expression like the below:
=1/8 x (7/1+64/1)
=1/8 x (7 + 64)

step 7Simplify the above expression further:
=1/8 x 71
=71/8
7/8+8=71/8

Hence,
7/8 plus 8 equals to 71/8 in fraction.

Problem and Workout - Cross Multiplication Method
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/8
Fraction B: 8/1

What to be found?
7/8+8 = ?
Find what's the sum of 7/8 and 8.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 1), find the product of numerator of Fraction B and denominator of Fraction A (8 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 1) and rewrite the equation as like the below:
= (7 x 1) + (8 x 8)/(8 x 1)

step 3 Simplify and rewrite the fraction:
= (7 + 64)/8
7/8+8 = 71/8
Hence,
7/8 plus 8 = 71/8
