①0.93×1.01②6.24-3.34-2.66③0.485×102-48.5④4.4+4.4×12+13×5.6(用简便方法)
是求最后等于,要用简便计算,用递等式.加油,

①0.93×1.01
=0.93*(1+0.01)
=0.93*1+0.93*0.01
=0.93+0.0093
=0.9393
②6.24-3.34-2.66
=6.24-(3.34+2.66)
=6.24-6
=0.24
③0.485×102-48.5
=48.5*1.02-48.5
=48.5*(1.02-1)
=48.5*0.02
=0.97
④4.4+4.4×12+13×5.6
=4.4*(1+12)+13×5.6
=13*(4.4+5.6)
=13*10
=130
