Respuesta:
a) 81/20 = 4 1/20
b) 82/15 = 5 7/15
c)19/9= 2 1/9
d)43/8 = 5 3/8
Explicación paso a paso:
a) 6 ¾- 2 ⁷/10= 27/4 - 27/10
27/4-27/10 = 5(27/4)-2(27/10) = 135/20 - 54/20
135/20 - 54/20= 81/20 =
b) 1 ⅔ + 3 ⅘= 5/3+ 19/5
5(5/3)+3(19/5) = 25/15+ 57/15 = 82/15
c) 2 ⁵/9 - ⁴/9= 23/9- 4/9 = 19/9
d) 4 ¾ + ⅝= 19/4+5/8
2(19/4)+1(5/8) = 38/8+5/8=43/8
