The LCM of 9 and 16 is 144.
step 4 Write the fractions 7/9 and 5/16 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/9-5/16
=(7 x 144)/(9 x 144)-(5 x 144)/(16 x 144)
step 5 Simplify the expression to have common denominator:
=112/144-45/144
step 6 Take the common values out and rewrite the above expression like the below:
=1/144 x (112/1-45/1)
=1/144 x (112 - 45)
step 7Simplify the above expression further:
=1/144 x 67
=67/144
7/9-5/16=67/144
