答案:
解析:
这些题目都是基础的分数加减法和分数与整数的乘法题目。
对于分数的加减法,需要找到通分母,或者进行分数的化简。
对于分数与整数的乘法,直接应用公式 $\frac{a}{b} × c = \frac{a × c}{b}$ 进行计算。
答案:
$\frac{1}{6} + \frac{1}{2} = \frac{1+3}{6} = \frac{4}{6} = \frac{2}{3}$
$\frac{8}{9} × 5 = \frac{8 × 5}{9} = \frac{40}{9}$
$\frac{2}{3} + 6 = \frac{2+18}{3} = \frac{20}{3} = 6\frac{2}{3}$
$\frac{5}{24} × 16 = \frac{5 × 16}{24} = \frac{80}{24} = \frac{10}{3} = 3\frac{1}{3}$
$\frac{11}{18} × 19 = \frac{11 × 19}{18} = \frac{209}{18} = 11\frac{11}{18}$
$\frac{2}{15} + \frac{2}{3} = \frac{2+10}{15} = \frac{12}{15} = \frac{4}{5}$
$\frac{4}{9} × 15 = \frac{4 × 15}{9} = \frac{60}{9} = \frac{20}{3} = 6\frac{2}{3}$
$\frac{1}{2} + \frac{1}{2} = \frac{1+1}{2} = 1$
$\frac{2}{11} × 22 = \frac{2 × 22}{11} = 4$
$\frac{1}{3} × 9 = \frac{1 × 9}{3} = 3$
$56 × \frac{3}{7} = \frac{56 × 3}{7} = 24$
$\frac{2}{41} × 82 = \frac{2 × 82}{41} = 4$
$\frac{4}{11} × 22 = \frac{4 × 22}{11} = 8$
$84 × \frac{1}{7} = \frac{84}{7} = 12$
$1 - \frac{5}{12} = \frac{12-5}{12} = \frac{7}{12}$
$\frac{2}{9} + \frac{5}{9} = \frac{2+5}{9} = \frac{7}{9}$
$28 × \frac{4}{7} = \frac{28 × 4}{7} = 16$
$16 × \frac{7}{8} = \frac{16 × 7}{8} = 14$
$\frac{3}{8} × 72 = \frac{3 × 72}{8} = 27$
$\frac{1}{3} + \frac{3}{4} = \frac{4+9}{12} = \frac{13}{12} = 1\frac{1}{12}$
$\frac{5}{6} × 24 = \frac{5 × 24}{6} = 20$
