Answer 2

Respuesta:

1 3/5 + 2 3/4 = 87 / 20

2 4/7 - 1 5/6 = 31/42

Explicación paso a paso:

1 3/5

= 1 + 3/5

= 5/5 + 3/5

= ( 5 + 3 ) / 5

= 8/5

2 3/4

= 2 + 3/4

= 8/4 + 3/4

= ( 8 + 3 ) / 4

= 11/4

1 3/5 + 2 3/4

= 8/5 + 11/4

8/5

= ( 8 / 5 ) x ( 4 / 4 )

= ( 8 x 4 ) / ( 5 x 4 )

= 32/20

11/4

= ( 11 / 4 ) x ( 5 / 5 )

= ( 11 x 5 ) / ( 4 x 5 )

= 55/20

8/5 + 11/4

= 32/20 + 55/20

= ( 32 + 55 ) / 20

= 87/20

2 4/7

= 2 + 4/7

= 14/7 + 4/7

= ( 14 + 4 ) / 7

= 18/7

1 5/6

= 1 + 5/6

= 6/6 + 5/6

= ( 6 + 5 ) / 6

= 11/6

2 4/7 - 1 5/6

= 18/7 - 11/6

18/7

= ( 18 / 7 ) x ( 6 / 6 )

= ( 18 x 6 ) / ( 7 x 6 )

= 108/72

11/6

= ( 11 / 6 ) x ( 7 / 7 )

= ( 11 x 7 ) / ( 6 x 7 )

= 77/42

18/7 - 11/6

= 108/42 - 77/42

= ( 108 - 77 ) / 42

= 31/42
