2. Cross multiplication method.

(5/7) - (8/11) using LCM Method:
What is 5/7 minus 8/11 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 8/11

What to be found?
(5/7) - (8/11) = ?
Find what's the difference between 5/7 and 8/11.

step 2 Compare the denominators of fractions 5/7 and 8/11 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/7 and 8/11 are not equal, it is said to be unlike fractions subtraction.

step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 5/7 and 8/11:
The LCM of 7 and 11 is 77.

step 4 Write the fractions 5/7 and 8/11 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/7 - 8/11
= [(5 x 77)/(7 x 77)] - [(8 x 77)/(11 x 77)]

step 5 Simplify the expression to have common denominator:
= 55/77 - 56/77

step 6 Take the common values out and rewrite the above expression like the below:
= 1/77 x (55/1 - 56/1)
= 1/77 x (55 - 56)

step 7Simplify the above expression further:
= 1/77 x -1
= -1/77
5/7 - 8/11 = -1/77

Hence,
5/7 minus 8/11 as a fraction is -1/77.
