2. Cross multiplication method.
7/8-6/13 using LCM Method:
What is 7/8 minus 6/13 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/8
Fraction B: 6/13
What to be found?
7/8-6/13 = ?
Find what's the difference between 7/8 and 6/13.
step 2 Compare the denominators of fractions 7/8 and 6/13 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/8 and 6/13 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 7/8 and 6/13:
The LCM of 8 and 13 is 104.
step 4 Write the fractions 7/8 and 6/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/8-6/13
=(7 x 104)/(8 x 104)-(6 x 104)/(13 x 104)
step 5 Simplify the expression to have common denominator:
=91/104-48/104
step 6 Take the common values out and rewrite the above expression like the below:
=1/104 x (91/1-48/1)
=1/104 x (91 - 48)
step 7Simplify the above expression further:
=1/104 x 43
=43/104
7/8-6/13=43/104
Hence,
7/8 minus 6/13 equals to 43/104 in fraction.
