The LCM of 8 and 13 is 104.
step 4 Write the fractions 7/8 and 7/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/8-7/13
=(7 x 104)/(8 x 104)-(7 x 104)/(13 x 104)
step 5 Simplify the expression to have common denominator:
=91/104-56/104
step 6 Take the common values out and rewrite the above expression like the below:
=1/104 x (91/1-56/1)
=1/104 x (91 - 56)
step 7Simplify the above expression further:
=1/104 x 35
=35/104
7/8-7/13=35/104
Hence,
7/8 minus 7/13 equals to 35/104 in fraction.
