用递等式计算:2.6×(2.139÷9.3×6.2)16.75-(9.1-1.92)+1.622.6×1.9÷2.6×1.94.264÷(0.16×20.5)
用递等式计算:2.6×(2.139÷9.3×6.2)16.75-(9.1-1.92)+1.622.6×1.9÷2.6×1.94.264÷(0.16×20.5)
(1)2.6×(2.139÷9.3×6.2)
=2.6×(0.23×6.2)
=2.6×1.426
=3.7076;
(2)16.75-(9.1-1.92)+1.62
=16.75-7.18+1.62
=9.57+1.62
=11.19;
(3)2.6×1.9÷2.6×1.9
=2.6÷2.6×1.9×1.9
=1×1.9×1.9
=3.61;
(4)4.264÷(0.16×20.5)
=4.264÷3.28
=1.3
