Question

4-Calcule:
a)(3/2)-2
b)(1/2) =
c)(2/3)-2=
d)(-1/4)-2
e)(5/2)-3=
f) (-1/2)-4 =​

Answer 1

Resposta:

4)

$a)\frac{3}{2} -2=\frac{3}{2} -\frac{2}{1} = \frac{3}{2} - \frac{4}{2} =-\frac{1}{2}$

$b) \frac{1}{2}$

$c) \frac{2}{3} -2=\frac{2}{3}-\frac{2}{1} = \frac{2}{3} - \frac{6}{3} =-\frac{4}{3}$

$d) -\frac{1}{4} -2=-\frac{1}{4}-\frac{2}{1} = -\frac{1}{4} -\frac{8}{4} = -\frac{9}{4}$

$e) \frac{5}{2} -3= \frac{5}{2} -\frac{3}{1} = \frac{5}{2} -\frac{6}{2} = -\frac{1}{2}$

$f) -\frac{1}{2} -4= -\frac{1}{2} -\frac{4}{1} = -\frac{1}{2} -\frac{8}{2} =- \frac{9}{2}$
