數(shù)學(xué):
1.尋找失去的數(shù).
14.59+10.72-25.31=0 49.81-48.32+78.51=80
2.求未知量.
解:a=s÷h 解：h=2s÷a
=5.52÷1.2 =2×5.25÷ 2.5
=4.6(m) =10.5÷2.5
=4.2(dm)
3.找出等量關(guān)系，并列方程解答.
(1)820減去一個(gè)數(shù)的16倍等于45.5與8的積,求這個(gè)數(shù).
解:設(shè)這個(gè)數(shù)是x.
820-16x=45.5×8
820-16x=364
16x=820-364
16x=456
x=28.5
(2)一個(gè)數(shù)減去6后,擴(kuò)大7倍等于這個(gè)數(shù)的2倍,求這個(gè)數(shù).
解:設(shè)這個(gè)數(shù)是x.
7(x-6)=2x
7x-42=2x
7x-2x=42
5x=42
x=8.4
4.寫(xiě)出下列各圖案的數(shù)字.

數(shù)學(xué):
1.下列各題錯(cuò)在哪里?請(qǐng)改正.
1.73×3.7+1.73×6.3+1.73 0.125×6.4
=1.73×(3.7+6.3)+1.73 =(0.125×8)×0.8
=1.73×10+1.73 =1×0.8
=17.3+1.73 =0.8
=19.03
2.化簡(jiǎn).
4×3×2×b=24b 8m×3=24m 44b÷4=11b
4×25x=100x 6×4x+x-5=25x-5 7×3x+4×5y-15=21x+20y-15
3.求值:當(dāng)k=19,m=4,n=5時(shí)，求k(3m+6n)的值.
解：當(dāng)k=19,m=4,n=5時(shí)
k(3m+6n)=19×(3×4+6×5)
=19×(12+30)
=19×42
=798
4.不計(jì)算，在下面的□填入“>、<”或“=”。
4.7×2.01>4.7 0.28÷0.5>0.28
4.7×1=4.7 0.28÷3.5<0.28
4.7×0.01<4.7 0.28÷0.01>0.28
動(dòng)腦筋：
解:設(shè)小長(zhǎng)方形的寬為x,則長(zhǎng)方形為2x.
2(3x+2x)=8 S長(zhǎng)=(3×0.8)×(2×0.8)
5x×2=8 =2.4×1.6
10x=8 =3.84(dm2)
x=0.8

數(shù)學(xué):
1.計(jì)算并湊整倒百分位(用四舍五入法).
8.02×0.04≈0.32 7.83×1.39≈10.88
8.02 7.83

2.遞等式計(jì)算(能簡(jiǎn)則簡(jiǎn)).
6.4×0.29+6.4×8.7+6.4 2.98×1.25×(4-0.8)×0.25
=6.4×(0.29+8.7+1) =2.98×1.25×3.2×0.25
=6.4×10 =2.98×1.25×0.4×8×0.25
=64 =(1.25×8)×(0.25×0.4)×2.98
=10×0.1×2.98
=2.98
9.9×101-9.9 [0.68÷(3.2-3.03)+1.4÷(6-0.6)
=9.9×(101-1) =[0.68÷0.17+1.4]÷5.4
=9.9×100 =[4+1.4]÷5.4
=990 =5.4÷5.4
=1
3.列方程解應(yīng)用題.
小丁丁買(mǎi)了1支圓珠筆和1支鋼筆,鋼筆的售價(jià)是圓珠筆的3倍,小丁丁共付了18元,圓珠筆和鋼筆的售價(jià)各式多少元?
