仔细计算.①233×4﹣133②4.62+9.9+5.38+0.1③4×0.6+0.6÷④36×(﹣)+15⑤+(0.4﹣)×4.5⑥0.9与0.2的差加上1除以1.25的商是多少?⑦(在括号里填上不同的自然数)
2.7+4.6=0 6﹣0.06= 10﹣4.56= 2.4×0.3=1.4÷0.01= 0.51÷0.3= 5.6÷(3.74﹣3.73)= 14.09﹣7.54﹣6.46=
看谁算得快.0.55+0.45= 7﹣1.036= 50×0.25= 0.25×400=1.3+0.13= 6.3×101= 1.5+2.26+0.5= 0.8+0.2﹣0.8+0.2=(5.25﹣4)×8= 4×0.37×0.25=
直接写出得数.0.2×8= 12.5×8= 6.2+0.04= 2.5×0.4=0.6×0.7= 6﹣0.7= 6.4+4.6= 0.04×0.3=0.5×2.4= 2.1﹣2.01= 11.5÷5= 0.4÷8=
直接写得数:5﹣0.32= ; 0.3÷1.5= ; 0.06×1.3= ; 4×4÷4×4= ;5×0.8= ; 12÷6= ; 20×3.6= ; 36×99+36= .
