(1)16.2÷(48.6+5.4)×0.5
=16.2÷54×0.5
=0.3×0.5
=0.15
(2)0.36÷[(6.1-4.6)×0.8]
=0.36÷[1.5×0.8]
=0.36÷1.2
=0.3
(3)2.38÷(59.5÷0.25)
=2.38÷238
=0.01
(4)37.6-1.5÷0.24
=37.6-6.25
=31.35
=16.2÷54×0.5
=0.3×0.5
=0.15
(2)0.36÷[(6.1-4.6)×0.8]
=0.36÷[1.5×0.8]
=0.36÷1.2
=0.3
(3)2.38÷(59.5÷0.25)
=2.38÷238
=0.01
(4)37.6-1.5÷0.24
