Answer 2

Respuesta:

396 / 28

Explicación paso a paso:

20 / 4

= 5

= 5 / 1

= ( 5 / 1 ) x ( 28 / 28 )

= ( 5 x 28 ) / ( 1 x 28 )

= 140 / 28

5 / 2

= ( 5 / 2 ) x ( 14 / 14 )

= ( 5 x 14 ) / ( 2 x 14 )

= 70 / 28

36 / 8

= 9 / 2

= ( 9 / 2 ) x ( 14 / 14 )

= ( 9 x 14 ) / ( 2 x 14 )

= 126 / 28

15 / 7

= ( 15 / 7 ) x ( 4 / 4 )

= ( 15 x 4 ) / ( 7 x 4 )

= 60 / 28

20 / 4 + 5 / 2 + 36 / 8 + 15 / 7

= 140 / 28 + 70 / 28 + 126 / 28 + 60 / 28

= ( 140 + 70 + 126 + 60 ) / 28

= 396 / 28
