b ) 7/2

Explicación paso a paso:

a )

( 2/3 + 4/6 ) : 1/2

2/3 + 4/6

2/3

= 2/3 x 2/2

= ( 2 x 2 ) / ( 3 x 2 )

= 4/6

2/3 + 4/6

= 4/6 + 4/6

= ( 4 + 4 )/6

= 8/6

( 2/3 + 4/6 ) : 1/2

= 8/6 : 1/2

= 8/6 x 2

= 16/6

= 8/3

b )

5/3 : 1/2

= 5/3 x 2

= 10/3

2/3 . 1/4

= 2/3 . 1/( 2 x 2 )

= 1/3 . 1/2

= 1/6

( 5/3 : 1/2 ) + ( 2/3 . 1/4 )

= 10/3 + 1/6

10/3

= 10/3 x 2/2

= 20/6

10/3 + 1/6

= 20/6 + 1/6

= ( 20 + 1 )/6

= 21/6

= 7/2
