Answer 1

五年级下期分数脱式计算题如下： 408－12×24 = 408 - 288 = 120 （46＋28）×60 = 74 x 60 = 4440 42×50－17 = 2100- 17 = 2083 32＋105÷5 = 32 + 21 = 53 420×（327－238） = 420 x 89 = 37380 (4121+2389)÷7 = 6510 ÷7 = 930 3.416÷（0.016×35） = 3.416 ÷0.56 = 6.1 0.8×[(10－6.76)÷1.2] = 0.8 x(3.24÷1.2) = 0.8 x 2.7 = 2.16 5.67×0.2-0.62 = 1.134-0.62 = 0.514 0.4×0.7×0.25 = 0.4 x 0.25 x 0.7 = 0.1 x 0.7 = 0.07 0.78+5.436+1 = 6.216 +1 = 7.216 30.8÷[14－(9.85＋1.07)] = 30.8 ÷ (14 - 10.92) = 30.8÷3.08 = 10 [60－(9.5＋28.9)]÷0.18 = (60- 38.4)÷0.18 = 21.6 ÷0.18 = 120 2.881÷0.43－0.24×3.5 = 6.7 - 0.24 x3.5 = 6.7 - 0.84 = 5.86 3/4+1/6-2/3=1/4 7/8-1/4+4/9=77/72 1-1/3+2/7=20/21 1/2+4/5-3/10=1 5/6-(2/3-1/9)=5/18 9/10-(3/4+1/8)=1/40 1/2+2/3-3/4=5/12 7/8-1/6+1/4=23/24 1-(3/4-2/9)=17/36 9/10-1/5-1/2=1/5 1/4+3/7+1/2=33/28 7/8-(2/3+1/6)=1/24 1-(1/3+3/5)=1/15 1/2+1/4+1/3=13/12 7/8+1/4+1/2=5/8 5/7-(4/7+1/9)=2/63 1-1/4-1/2=1/4 3/4-1/6-1/3=1/4 3/10+1/4+2/5=19/20 2/3+1/6+1/12=11/12 1-1/4-2/5=7/20 1/2+1/9+1/12=25/36 125×(97-81) =125x16 =2000 6942+480÷3 = 6942 + 160 = 6782 20+80÷4-20 = 20 + 20 -20 = 40 -20 = 20 100÷（32-30）×0 = 100 ÷2 x0= 50 x0 = 0
