100+6.23+3.68-37.75

=100+6.12+0.11+3.68-37.75

=100+(6.12+3.68)+0.11-37.75

=100+10+0.11-37.75

=110.11-37.75

=72.16

(11/16÷1/2+15/16)×8/9

=(11/16×2+15/16)×8/9

=(22/16+15/16)×8/9

=27/16×8/9

=3/2

8.1÷【(29/7-0.005×700)÷9/7】

=8.1÷【(29/7-7/2)×7/9】

=8.1÷(29/7×7/9-7/2×7/9)

=8.1÷(29/9-49/18)

=8.1÷1/2

=8.1x2

=16.2
