Question

ayudaaaaaaaaaaaaaaaaaa​

Answer 1

Explicación paso a paso:

La suma o resta de fracciones es una de las operaciones básicas que permite combinar dos o más fracciones

1.

$\frac{13}{2} - \frac{1}{4}- \frac{5}{6}=\frac{(13)(6) -(1)(3) -(5)(2) }{12} =\frac{78-3-10}{12} =\frac{65}{12}$

2.

$\frac{-2}{11} + \frac{11}{2}- \frac{12}{11}=\frac{(-2)(2) +(11)(11) -(12)(2) }{22} =\frac{-4+121-24}{22} =\frac{93}{22}$

3.

$\frac{-5}{3} - \frac{4}{3}=\frac{(-5)-(4)}{3} =\frac{-9}{3} =-3$

4.

$\frac{-3}{12} - \frac{2}{10}+ \frac{4}{10}=\frac{(-3)-(2)+(4)}{60} =\frac{-1}{12}$

5.

$\frac{-3}{9} + \frac{3}{9}=\frac{(-3)+(3)}{9} =\frac{0}{9} =0$

6.

$\frac{3}{5} + \frac{3}{15}- \frac{3}{10}=\frac{(3)(6) +(3)(2) -(3)(3) }{30} =\frac{18+6-9}{30} =\frac{15}{30} =\frac{1}{2}$

7.

$\frac{2}{3} + \frac{3}{2}=\frac{(2)(2) + (3)(3) }{6} =\frac{4+9}{6} =\frac{13}{6}$

8.

$\frac{-2}{22} + \frac{22}{2}- \frac{12}{11}=\frac{(-2)(1) +(22)(11) -(12)(2) }{22} =\frac{-2+242-24}{22} =\frac{216}{22} =\frac{108}{11}$

9.

$\frac{-6}{4} - \frac{4}{6}- \frac{1}{8}=\frac{(-6)(6) -(4)(4) -(1)(3) }{24} =\frac{-36-16-3}{24} =\frac{-55}{24}$

10.

$\frac{-3}{2} + \frac{-2}{3}=\frac{(-3)(3) + (-2)(2) }{6} =\frac{-9-4}{6} =\frac{-13}{6}$
