Bonjour,
[tex]A = \frac{16}{54} *\frac{35}{8}[/tex]
[tex]A = \frac{16*35}{54*8}[/tex]
[tex]A = \frac{560}{432}[/tex]
[tex]A = \frac{560 / 2}{432 / 2}[/tex]
[tex]A = \frac{280 / 2}{216 / 2}[/tex]
[tex]A = \frac{140 / 2}{108 / 2}[/tex]
[tex]A = \frac{70 / 2}{54 / 2}[/tex]
[tex]A = \frac{35}{27}[/tex]
[tex]B = -\frac{4}{3} + \frac{11}{12} / \frac{22}{18}[/tex]
[tex]B = -\frac{4}{3} + \frac{11}{12} * \frac{18}{22}[/tex]
[tex]B = -\frac{4}{3} + \frac{11*18}{12*22}[/tex]
[tex]B = -\frac{4}{3} + \frac{198}{264}[/tex]
[tex]B = -\frac{4*264}{3*264} + \frac{198*3}{264*3}[/tex]
[tex]B = -\frac{1056}{792} + \frac{594}{792}[/tex]
[tex]B = \frac{- 1056+594}{792}[/tex]
[tex]B =- \frac{462}{792}[/tex]
[tex]B =- \frac{7}{12}[/tex]
[tex]C = \frac{7}{15} -\frac{2}{15} *\frac{25}{14}[/tex]
[tex]C = \frac{7}{15} -\frac{2*25}{15*14}[/tex]
[tex]C = \frac{7}{15} -\frac{50}{210}[/tex]
[tex]C = \frac{7}{15} -\frac{5}{21}[/tex]
[tex]C = \frac{7*21}{15*21} -\frac{5*15}{21*15}[/tex]
[tex]C = \frac{147}{315} -\frac{75}{315}[/tex]
[tex]C = \frac{147-75}{315}[/tex]
[tex]C = \frac{72}{315}[/tex]
[tex]C = \frac{8}{35}[/tex]
[tex]D = \frac{3}{4} +\frac{5}{4} / (\frac{4}{3} - \frac{1}{2} )[/tex]
[tex]D = \frac{3}{4} +\frac{5}{4} / \frac{5}{6}[/tex]
[tex]D = \frac{3}{4} +\frac{5}{4} * \frac{6}{5}[/tex]
[tex]D = \frac{3}{4} +\frac{30}{20}[/tex]
[tex]D = \frac{3}{4} +\frac{30}{20}[/tex]
[tex]D = \frac{3}{4} +\frac{3}{2}[/tex]
[tex]D = \frac{9}{4}[/tex]
