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

Resuelve las operaciones:  

• 2/4 + 3/5 + 1/3 =

$\frac{2}{4} + \frac{3}{5}+ \frac{1}{3}=\frac{(2)(15) +(3)(12) +(1)(20) }{60} =\frac{30+36+20}{60} =\frac{86}{60} =\frac{43}{30}$

• 5/2 - 4/5 + 8/6 =

$\frac{5}{2} - \frac{4}{5}+ \frac{8}{6}=\frac{(5)(15) -(4)(6) +(8)(5) }{30} =\frac{75-24+40}{30} =\frac{91}{30}$

• 6/2 + 3/4 + 5/3 =

$\frac{6}{2} + \frac{3}{4}+ \frac{5}{3}=\frac{(6)(6) +(3)(3) +(5)(4) }{12} =\frac{36+9+20}{12} =\frac{65}{12}$

• 6/3 + 5/4 + 1/2 =

$\frac{6}{3} + \frac{5}{4}+ \frac{1}{2}=\frac{(6)(4) +(5)(3) +(1)(6) }{12} =\frac{24+15+6}{12} =\frac{45}{12} =\frac{15}{4}$

• 9/3 + 4/3 + 2/3 =

$\frac{9}{3} + \frac{4}{3}+ \frac{2}{3}=\frac{(9)+(4)+(2)}{3} =\frac{15}{3} =5$

• 5/1 - 7/4 + 5/3 =​

$\frac{5}{1} - \frac{7}{4}+ \frac{5}{3}=\frac{(5)(12) -(7)(3) +(5)(4) }{12} =\frac{60-21+20}{12} =\frac{59}{12}$
