分析:通過計算可求各個算式的值,再根據整數(shù)大小的比較方法:比較兩個整數(shù)的大小,要看它們的數(shù)位,如果數(shù)位不同,那么數(shù)位多的數(shù)就大,如果數(shù)位相同,相同數(shù)位上的數(shù)大的那個數(shù)就大.
解答:解:W:7×356+1800,
=2492+1800,
=4292;
a:236×5+280,
=1180+280,
=1460;
n:336×5+170,
=1680+170,
=1850;
g:230×9+2320,
=1070+2320,
=3390;
m:188×7+230,
=1316+230,
=1546;
c:223+5×98,
=223+490,
=713;
e:5×604+1350,
=3020+1350,
=4370;
l:167×5+165,
=835+165,
=1000;
h:678-67×8,
=678-536,
=142;
i:5×604-126,
=3020-126,
=2894.
因為4370>4292>3390>2894>1850>1546>1460>1000>713>142,
所以e>w>g>i>n>m>a>l>c>h.
如圖所示:
點評:做此類比較數(shù)的大小的題時,要看它們的數(shù)位,如果數(shù)位不同,那么數(shù)位多的數(shù)就大,如果數(shù)位相同,相同數(shù)位上的數(shù)大的那個數(shù)就大.
