(1)13.01÷0.25÷0.4(2)37.65×3.4+37.65×6.6
(3)1.2×0.4+1.3×0.4(4)10.8×0.8÷0.27
答案

(1)原式=13.01÷(0.25×0.4)

                =13.01÷0.1

                =130.1(2)原式=37.65×(3.4+6.6)

                =37.65×10

                =376.5

(3)原式=(1.2+1.3)×0.4

               =2.5×0.4

               =1(4)原式=10.8÷0.27×0.8
