一间仓库的长是8米,宽是6米,高是3米。如果给仓库的墙壁和屋顶刷涂料,粉刷的面积是多少?
答案:
$(8×3+6×3)×2+8×6=132$(平方米) 答:粉刷的面积是132平方米。
1. 直接写得数。
$\frac {1}{12}÷12=$ $0÷\frac {3}{2}=$ $24×\frac {5}{6}=$ $\frac {7}{24}×\frac {6}{14}=$
$\frac {5}{6}÷\frac {6}{5}=$ $\frac {1}{3}÷\frac {3}{8}=$ $\frac {8}{25}÷\frac {4}{5}=$ $\frac {4}{9}÷\frac {3}{8}=$
$\frac {8}{21}×\frac {7}{16}=$ $9÷\frac {9}{11}=$ $1÷\frac {1}{2}=$ $\frac {3}{4}×\frac {8}{3}=$
$\frac {1}{9}×5=$ $\frac {4}{7}×\frac {2}{4}=$ $12×\frac {5}{6}=$ $\frac {4}{5}×\frac {3}{4}=$
$\frac {1}{12}÷12=$ $0÷\frac {3}{2}=$ $24×\frac {5}{6}=$ $\frac {7}{24}×\frac {6}{14}=$
$\frac {5}{6}÷\frac {6}{5}=$ $\frac {1}{3}÷\frac {3}{8}=$ $\frac {8}{25}÷\frac {4}{5}=$ $\frac {4}{9}÷\frac {3}{8}=$
$\frac {8}{21}×\frac {7}{16}=$ $9÷\frac {9}{11}=$ $1÷\frac {1}{2}=$ $\frac {3}{4}×\frac {8}{3}=$
$\frac {1}{9}×5=$ $\frac {4}{7}×\frac {2}{4}=$ $12×\frac {5}{6}=$ $\frac {4}{5}×\frac {3}{4}=$
答案:
$\frac{1}{144}$ 0 20 $\frac{1}{8}$ $\frac{25}{36}$ $\frac{8}{9}$ $\frac{2}{5}$ $\frac{32}{27}$ $\frac{1}{6}$ 11 2 2 $\frac{5}{9}$ $\frac{2}{7}$ 10 $\frac{3}{5}$
2. 计算下面各题,怎样计算简便就怎样计算。
$3×(\frac {2}{15}+\frac {1}{12})-\frac {1}{4}$ $\frac {5}{6}÷\frac {5}{12}+\frac {7}{15}×\frac {3}{7}$
$\frac {9}{17}÷9+\frac {1}{9}×\frac {8}{17}$ $(\frac {1}{2}-\frac {3}{8})÷\frac {3}{4}$
$(\frac {3}{7}-\frac {5}{12})-(\frac {7}{12}-\frac {4}{7})$ $\frac {4}{5}÷[\frac {5}{8}×(1-\frac {1}{5})]$
$3×(\frac {2}{15}+\frac {1}{12})-\frac {1}{4}$ $\frac {5}{6}÷\frac {5}{12}+\frac {7}{15}×\frac {3}{7}$
$\frac {9}{17}÷9+\frac {1}{9}×\frac {8}{17}$ $(\frac {1}{2}-\frac {3}{8})÷\frac {3}{4}$
$(\frac {3}{7}-\frac {5}{12})-(\frac {7}{12}-\frac {4}{7})$ $\frac {4}{5}÷[\frac {5}{8}×(1-\frac {1}{5})]$
答案:
$\frac{2}{5}$ $\frac{11}{5}$ $\frac{1}{9}$ $\frac{1}{6}$ 0 $\frac{8}{5}$
