9.13+16.5______24.16-7.2.
答案
(1)由于3.8+24.6=28.4,35.12+4.44=39.56,
28.4<39.56,
则3.8+24.6<35.12+4.44;
(2)由于12.34-2.9=9.44,8.7+5.1=13.6,
9.44<13.6,
则12.34-2.9<8.7+5.1;
(3)由于46.76-5.13=41.63,13.47+20.62=34.09,
41.63>34.09,
则46.76-5.13>13.47+20.62;
(4)由于9.13+16.5=15.63,24.16-7.2=16.96,
15.63<16.96,
则9.13+16.5<24.16-7.2.
