Explicación paso a paso:

una pregunta como seria la respuesta

7/5 - 16/15

$\frac{7}{5} - \frac{16}{15}=\frac{(7)(3) -(16)(1) }{15} =\frac{21-16}{15} =\frac{5}{15} =\frac{1}{3}$

11/6 - 3/2

$\frac{11}{6} - \frac{3}{2}=\frac{(11)(1) -(3)(3) }{6} =\frac{11-9}{6} =\frac{2}{6} =\frac{1}{3}$

21/20-7/20

$\frac{21}{20} - \frac{7}{20}=\frac{(21)-(7)}{20} =\frac{14}{20} =\frac{7}{10}$

9/5-9/5

$\frac{9}{5} - \frac{9}{5}=\frac{(9)-(9)}{5} =\frac{0}{5} =0$

5/4-1/4

$\frac{5}{4} - \frac{1}{4}=\frac{(5)-(1)}{4} =\frac{4}{4} =1$

36/13-28/13

$\frac{36}{13} - \frac{28}{13}=\frac{(36)-(28)}{13} =\frac{8}{13}$

4/3-4/3

$\frac{4}{3} - \frac{4}{3}=\frac{(4)-(4)}{3} =\frac{0}{3} =0$

7/10-1/2

$\frac{7}{10} - \frac{1}{2}=\frac{(7)(1) -(1)(5) }{10} =\frac{7-5}{10} =\frac{2}{10} =\frac{1}{5}$

29/18-7/9

$\frac{29}{18} - \frac{7}{9}=\frac{(29)(1) -(7)(2) }{18} =\frac{29-14}{18} =\frac{15}{18} =\frac{5}{6}$

13/8-17/16

$\frac{13}{8} - \frac{17}{16}=\frac{(13)(2) -(17)(1) }{16} =\frac{26-17}{16} =\frac{9}{16}$

25/12-5/3

$\frac{25}{12} - \frac{5}{3}=\frac{(25)(1) -(5)(4) }{12} =\frac{25-20}{12} =\frac{5}{12}$

34/15-11/5

$\frac{34}{15} - \frac{11}{5}=\frac{(34)(1) -(11)(3) }{15} =\frac{34-33}{15} =\frac{1}{15}$
