Question

5/12 mas 3/4=
4/3 mas 8/9=
68.8 mas 1/2=
1 entero 1/2 mas 2 enteros 1/3=
3 enteros 1/4 mas 4 enteros 1/3=
5 enteros 2/3 mas 8 enteros 1/2=

Answer 1

5/12 mas 3/4=$\frac{5}{12}+ \frac{3}{4} = \frac{5+9}{12} = \frac{14}{12} = \frac{7}{6}$
4/3 mas 8/9=
$\frac{4}{3}+ \frac{8}{9}= \frac{12+8}{9} = \frac{20}{9}$
68.8 mas 1/2=
$\frac{688}{10} + \frac{1}{2} = \frac{688+5}{10} = \frac{693}{10} =69.3$
1 entero 1/2 mas 2 enteros 1/3=
$\frac{3}{2} + \frac{7}{3} = \frac{9+14}{6} = \frac{23}{6}$
3 enteros 1/4 mas 4 enteros 1/3=
$\frac{13}{4} + \frac{13}{3} = \frac{29+52}{12} = \frac{81}{12} = \frac{27}{4}$
5 enteros 2/3 mas 8 enteros 1/2=
$\frac{17}{3} + \frac{17}{2} = \frac{34+51}{6} = \frac{85}{6}$
Un placer ayudarte ^^ Espero que te sirva :)

Answer 2

(1)en decimales es 14.166
(2)y en fraccion es 14 enteros 1/6
(1)porque al dividir 2/3= 0.666, 1/2=0.5, 8+5=13: entonces 13+0.5+0.666=14.166
(2)y en la fraccion porque al sumar 5+8=13, y 2/3+1/2=7/6, si convertimos 7/6 en fraccion mixta el resultado seria 1entero 1/6, 1 entero 1/6+13=14 enteros 1/6
