⑥4.4+4.4×12+13×5.6,轉(zhuǎn)化為:4.4×13+13×5.6,運(yùn)用乘法分配律簡(jiǎn)算.
解答:解:①9÷0.125
=(9×8)÷(0.125×8)
=72÷1
=72;
②25.25×0.65×4÷0.65
=25.25×4×(0.65÷0.65)
=101×1
=101;
③0.93×1.01,
=0.93×(1+0.01)
=0.93×1+0.93×0.01
=0.93+0.0093
=0.9393;
④6.24-3.34-2.66
=6.24-(2.34+2.66)
=6.24-5
=1.24;
⑤48.5×101-48.5
=48.5×(101-1)
=48.5×100
=4850;
⑥4.4+4.4×12+13×5.6
=4.4×13+13×5.6
=(4.4+5.6)×13
=10×13
=130.
點(diǎn)評(píng):此題考查的目的是理解掌握乘法的運(yùn)算定律、乘、除法、減法的運(yùn)算性質(zhì),并且能夠靈活運(yùn)用這些運(yùn)算定律和運(yùn)算性質(zhì)進(jìn)行簡(jiǎn)便計(jì)算.
