step 4 Write the fractions 16/11 and 7/20 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 16/11 - 7/20
= [(16 x 220)/(11 x 220)] - [(7 x 220)/(20 x 220)]

step 5 Simplify the expression to have common denominator:
= 320/220 - 77/220

step 6 Take the common values out and rewrite the above expression like the below:
= 1/220 x (320/1 - 77/1)
= 1/220 x (320 - 77)

step 7Simplify the above expression further:
= 1/220 x 243
= 243/220
16/11 - 7/20 = 243/220
