Answer 1

Respuesta:

2 / 25

129 / 50

Explicación paso a paso:

4 / 5

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

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

= 20 / 25

22 / 25 - 4 / 5

= 22 / 25 - 20 / 25

= ( 22 - 20 ) / 25

= 2 / 25

7 / 10

= ( 7 / 10 ) x ( 5 / 5 )

= ( 7 x 5 ) / ( 5 x 10 )

= 35 / 50

22 / 25

= ( 22 / 25 ) x ( 2 / 2 )

= ( 22 x 2 ) / ( 2 x 25 )

= 44 / 50

4 / 5

= ( 4 / 5 ) x ( 10 / 10 )

= ( 4 x 10 ) / ( 5 x 10 )

= 40 / 50

7 / 10 + 22 / 25 + 4 / 5

= 35 / 50 + 44 / 50 + 40 / 50

= ( 35 + 44 + 40 ) / 50

= 129 / 50
