1. 直接写出得数。
$5 - 0.6 =$
$2.7 + 7.3 =$
$0.12 × 0 =$
$8.5 - 0.24 - 1.76 =$
$2 × 0.07 =$
$10 × 0.45 =$
$7.3 - \frac{3}{5} =$
$0.5 + 0.5 × 0.6 =$
$0.3 × 4 =$
$1.2 × 5 =$
$0.7 + 2.8 =$
$(6.3 - 0.14) ÷ 0.7 =$
$\frac{8}{5} + \frac{1}{3} =$
$\frac{5}{12} ÷ \frac{25}{36} =$
$\frac{1}{4} + \frac{1}{2} =$
$13 × \frac{5}{39} + \frac{1}{3} =$
$\frac{1}{15} × \frac{15}{4} =$
$\frac{1}{6} + \frac{1}{3} =$
$\frac{7}{22} × \frac{11}{35} =$
$(\frac{3}{4} + \frac{5}{8}) ÷ 0.5 =$
$\frac{5}{9} × \frac{3}{5} =$
$\frac{15}{26} ÷ 0.75 =$
$\frac{2}{65} × \frac{13}{24} =$
$\frac{5}{7} × \frac{7}{9} ÷ \frac{7}{9} =$

1. 4.4 10 0 6.5
0.14 4.5 6.7 0.8
1.2 6 3.5 8.8
$\frac{29}{15}$ $\frac{3}{5}$ $\frac{3}{4}$ 2
$\frac{1}{4}$ $\frac{1}{2}$ $\frac{1}{10}$ $\frac{11}{4}$
$\frac{1}{3}$ $\frac{10}{13}$ $\frac{1}{60}$ $\frac{5}{7}$

2. 计算下面各题，怎样算简便就怎样算。
$(5.6 + 0.32) ÷ 0.8$
$4.5 ÷ 2.5 × 101 - 1.8$
$(45.9 - 32.7) ÷ \frac{4}{5} ÷ \frac{5}{4}$
$\frac{10}{3} - 4 ÷ 11 - \frac{7}{11}$
$\frac{7}{8} ÷ ( \frac{7}{10} + \frac{4}{5} ) × 1.2$
$\frac{8}{49} ÷ [ \frac{10}{9} - ( \frac{1}{9} + \frac{3}{7} ) ]$

2. 7.4 180 13.2
$\frac{7}{3}$ $\frac{7}{10}$ $\frac{2}{7}$

计算:2024÷2024$\frac{2024}{2025}$ + $\frac{1}{2026}$。

原式 = $2024 ÷ \frac{2024×2025+2024}{2025}$
$+ \frac{1}{2026}$
$=2024×\frac{2025}{2024×2026}+\frac{1}{2026}$
$=\frac{2025}{2026}+\frac{1}{2026}$
$=1$
