$\frac{1}{3}×\frac{1}{4}=$
$\frac{1}{3}÷\frac{1}{4}=$
$8+\frac{13}{16}=$
$8-\frac{13}{16}=$
$8×\frac{13}{16}=$
$8÷\frac{13}{16}=$
$80×\frac{4}{5}=$
$\frac{15}{7}÷5=$
$\frac{1}{26}÷\frac{13}{4}=\frac{1}{26}×\frac{( )}{( )}=$

2. 脱式计算。（能简算的要简算）
$\frac{5}{12}÷\frac{1}{4}×\frac{4}{15}$
$\frac{5}{12}÷(\frac{1}{4}×\frac{4}{15})$
$\frac{4}{15}×40×\frac{7}{8}$
$\frac{13}{18}÷\frac{7}{9}÷\frac{21}{26}$
$\frac{7}{8}÷\frac{6}{5}+\frac{1}{8}×\frac{5}{6}$
$2.8×(\frac{1}{7}+\frac{3}{28})$
$\frac{11}{12}×7÷\frac{7}{12}$
$101×\frac{99}{102}$
答案：$\frac{5}{12}×4×\frac{4}{15}$
$=\frac{5}{3}×\frac{4}{15}$
$=\frac{4}{9}$
$\frac{5}{12}÷\frac{1}{15}$
$=\frac{5}{12}×15$
$=\frac{25}{4}$
$\frac{4}{15}×\frac{7}{8}×40$
$=\frac{7}{30}×40$
$=\frac{28}{3}$
$\frac{13}{18}×\frac{9}{7}×\frac{26}{21}$
$=\frac{13}{14}×\frac{26}{21}$
$=\frac{169}{147}$
$\frac{7}{8}×\frac{5}{6}+\frac{1}{8}×\frac{5}{6}$
$=(\frac{7}{8}+\frac{1}{8})×\frac{5}{6}$
$=1×\frac{5}{6}$
$=\frac{5}{6}$
$2.8×\frac{1}{7}+2.8×\frac{3}{28}$
$=0.4 + 0.3$
$=0.7$
$\frac{11}{12}×7×\frac{12}{7}$
$=\frac{11}{12}×12$
$=11$
$(102 - 1)×\frac{99}{102}$
$=102×\frac{99}{102}-\frac{99}{102}$
$=99-\frac{33}{34}$
$=98\frac{1}{34}$
