a ) - 11 / 10
b ) 13 / 35
c ) - 43 / 14
d ) 7 / 3
e ) - 1 / 4
f ) 13 / 8
Explicación paso a paso:
a )
- 6 / 10 - 2 / 4
= - 3 / 5 - 1 / 2
= - 6 / 10 - 5 / 10
= ( - 6 - 5 ) / 10
= - 11 / 10
b )
4 / 5 - 3 / 7
= 28 / 35 - 15 / 35
= ( 28 - 15 ) / 35
= 13 / 35
c )
5 / - 2 - 4 / 7
= - 5 / 2 - 4 / 7
= - 35 / 14 - 8 / 14
= ( - 35 - 8 ) / 14
= - 43 / 14
d )
8 / 4 + 1 / 3
= 2 / 1 + 1 / 3
= 6 / 3 + 1 / 3
= ( 6 + 1 ) / 3
= 7 / 3
e )
- 1 / 2 + 2 / 8
= - 1 / 2 + 1 / 4
= - 2 / 4 + 1 / 4
= ( - 2 + 1 ) / 4
= - 1 / 4
f )
10 / 5 + 8 / - 3
= 2 / 1 - 3 / 8
= 16 / 8 - 3 / 8
= ( 16 - 3 ) / 8
= 13 / 8
