四年级下册计算题集锦
一、直接写出得数。
7.5+3.08 = 3,2.99 = 3?1.5 = 6.5,3.8 =
2.7,0.27 = 4.2?0.06 = 6.3,0.4 = 4.8?24 = 0.673×0 = 1.25×8 = 0.01?0.001×0.1 = 3.6?1.2= 0.72?0.9= 2.6?13= 4.8?0.4= 4.4?4= 0.78?6= 7.2?0.4 = 1?0.25= 1.6?2= 4?5= 6.3?0.3= 8?0.5= 0.75?0.3= 0.47?4.7= 3.2?1.6= 0?8.6= 0.42?7 = 2?5 = 1?0.2 = 7?8 = 8.4?2.1 = 0.69?1 = 1.26?0.6 = 0.5?0.2 = 0.9×100?1000 = 12.4,(2.4，3.25)= 0.01?0.001×0.1 = 0.5×0.1?0.5×0.1 = 0.5×0.1?0.5×0.1 = 0.9×100?1000 = 42.4，7.6 = 1.58，2.42 = 23.5，76.5?0.25 = 7.8,5.6 = 1.25×4 = 34.6?0.2×4 = 0.24?0.3 = 7.8×0.5 = 1?0.2,1×0.2 = 57?5.7 = 8.1,0.05 = 0.2×0.5 = 0.12×4 = 10?2.5 3.02×100 = 0.25×8 = 9.9?1.1 = 3.5?0.7 = 0.9?0.09 = 0.56?10 = 7.5×0.1 = 8.08?8 = 2.6?1.3= 101×7.5 =
12.3—0.9= 1.5+3.8= 0.4×2.5= 8×1.25=
0.25+0.2= 6.3?0.9= 0?1.1= 4.8?0.24=
二、用竖式计算。(除不尽的得数保留两位小数)
3.06×6.9= 0.71 ×2.5= 0.468×7.5=
6.49×0.85= 205×24= 0.36×2.8=
15.3,7.89= 64.8+24.36= 2.07?0.23= 9.5?0.25= 1.7?3=
78.23?13= 45.45?0.45= 0.006 ?0.25= 13.208?0.26= 8.4?0.012= 1.25?0.25=
15.36?1.2= 8.93?3.8= 1.8?0.25=
4.48?0.35= 7.79?9.5= 36?64=
0.7624?76= 78.6?11= 5.63?7.8=
93.5?46=
三、解方程。
4x，x = 19.5 26.4,3x = 15.3 7x = 98
x,3×4 = 12 5x,x，14 = 18 2x,0.5×2 = 0. 4 x，2 x，9 = 17.4 7 y?3 = 8.19 54?2，3 a = 72 5.5 m,1.3 m = 12.6 9×3,1.7 x = 13.4 8 x,2.6 x = 37.
15.6-x=1.23 1.5x=2.25 32.8?x=4.1
x+5.1x=18.3 0.8x-1.6=3.2 3.5x - 2.1x=0.28
四、计算，能简便的要简便。
0.4?0.3 16.85?0.5,16.92 0.72?
0.5×4?0.5×4 (7.5,2.3×0.4)?0.01 2.6×(0.175?0.25) 9.4 ×[0.96?(5.4?0.9)] 19.6?,0.48?(5.4?0.9), 1.92×(2.3+10.5?15)
18?,0.6×(8-6.5), 2.125×1.5+7.875×1.5 7.32,4.37×0.9 4.05?0.05?0.81
0.048×90×0.46(保留两位小数。) 76.2?0.16,0.16(保留一位小数。) 1.25×32 0.56，3.48，0.44，6.52 2.8×(2.25，27.5?1.5) 5.8×7.6，7.6×4.2
145.3,58.6,41.4 [(5.1,3.6)?0.8,1]×0.09 22.25?(32?12.8) 2.16?0.9?0.3
4.8?0.4-2.1?21 0.175?25?0.4
3.91×2.8，6.09×2.8 3.5?0.5?0.7 1,(6.75,3.5)?13 12.5×4.64×0.8
(34.17?1.7，1.6)×0.3
