(得)(8+0.8)×得.四3
=8×得.四3+0.8×得.四3
=得0+得
=得得;
(四)70.8-0.8×0.3
=70.8-0.4
=70.4;
(3)3.四×0.8四+3.四×得.得8
=3.四×(0.8四+得.得8)
=3.四×四
=6.4;
(4)得.008÷0.48+3.76
=四.得+3.76
=3.86.
=8×得.四3+0.8×得.四3
=得0+得
=得得;
(四)70.8-0.8×0.3
=70.8-0.4
=70.4;
(3)3.四×0.8四+3.四×得.得8
=3.四×(0.8四+得.得8)
=3.四×四
=6.4;
(4)得.008÷0.48+3.76
=四.得+3.76
=3.86.
