(2-3/4+1/2)x(3-3/4)+1/16
=(8/4-3/4+2/4)×(12/4-3/4)+1/16
=7/4×9/4+1/16
=63/16+1/16
=64/16
=4
1/6+1/2x3/16+5/6
=1+3/32
=35/32
(114-4.2÷1/5)÷3/8
=(114-21)×8/3
=93×8/3
=248
1.78x4+1.2÷4/5
=71.2+1.2×5/4
=71.2+1.5
=72.7
1.6-(13/5+3.8)x8
=1.6-(2.6+3.8)×8
=1.6-6.4×8
=1.6-51.2
=-49.6
(2-3/4+1/2)x(3-3/4)+1/16
=(8/4-3/4+2/4)×(12/4-3/4)+1/16
=7/4×9/4+1/16
=63/16+1/16
=64/16

1/6+1/2x3/16+5/6
=1+3/32

(114-4.2÷1/5)÷3/8

1.6-(13/5+3.8)x8
=1.6-(2.6+3.8)×8
=1.6-6.4×8
=1.6-51.2
=-49.6
