解题过程如下,希望能帮到你的,望采纳:
16.2×99+16.12
=16.2×99+16.2-0.08
=16.2×(99+1)-0.08
=16.2×100-0.08
=1619.92
16.2x99+16.12简便计算如下:
16.2x99+16.12=16.2x99+16.2-0.08=16.2x(99+1)-0.08=1620-0.08=1619.92
16.2×99+16.12
=16.2×99+16.2 -0.08
=16.2x(99+1) -0.08
=16.2x100-0.08
=1620-0.08
=1619.92
16.2×99+16.12
=16.2×99+16.2-0.08
=16.2×(99+1)-0.08
=1620-0.08
=1619+1-0.08
=1619+0.92
=1619.92
16.2×99+16.12
=16.2×99+16.2-0.08
=16.2×(99+1)-0.08
=16.2×100-0.08
=1620-0.08
=1619.92
