Porfas estoy batallando mucho;(

Answer 1

Respuesta:

253 / 108

Explicación paso a paso:

2 / 3

= ( 2 / 3 ) x ( 56 / 56 )

= ( 2 x 56 ) / ( 3 x 56 )

= 112 / 168

3 / 4

= ( 3 / 4 ) x ( 42 / 42 )

= ( 3 x 42 ) / ( 4 x 42 )

= 126 / 168

5 / 7

= ( 5 / 7 ) x ( 24 / 24 )

= ( 5 x 24 ) / ( 7 x 24 )

= 120 / 168

5 / 8

= ( 5 / 8 ) x ( 21 / 21 )

= ( 5 x 21 ) / ( 8 x 21 )

= 105 / 168

2 / 3 + 3 / 4 + 5 / 7 - 5 / 8

= ( 2 / 3 ) + ( 3 / 4 ) + ( 5 / 7 ) - ( 5 / 8 )

= ( 112 / 168 ) + ( 126 / 168 ) + ( 120 / 168 ) - ( 105 / 168 )

= ( 112 + 126 + 120 - 105 ) / 168

= ( 358 - 105 ) / 168

= 253 / 108
