解答:
解:425+88=513 25×8=200 1÷1.25=0.8 0.28×50=14 1.4÷0.7=2
2×6.5=13
×
=1 (
+
)×30=11
×1÷
=1 4.4+2.6=7
+
=1
24×(
-
)=4 0.4+11.6+2=14 0÷0.87=0
0.4×(2.5-2.4)=0.04
故答案為:513,200,0.8,14,2,13,1,11,1,7,1
,4,14,0,0.04.
點(diǎn)評(píng):正確運(yùn)用四則運(yùn)算計(jì)算方法進(jìn)行計(jì)算,是本題考查知識(shí)點(diǎn),關(guān)鍵是計(jì)算結(jié)果要準(zhǔn)確.
