Answer 1

(2 1/2 : 1/4) +(0,25 x 4/5)
= (5/2 : 1/4) +(25/100 x 4/5)
= (5/2 x 4) +(100/500)
= 20/2 +100/500
= 5000/500 +100/500
= 5100/500
= 10 100/500
= 10 1/5

Jadi, jawabannya adalah d.

Answer 2

( 2 1/2 : 1/4 ) + ( 0,25 × 4/5 )
= ( 5/2 : 1/4 ) + ( 25/100 × 4/5 )
= ( 5/2 × 4/1 ) + ( 25/100 × 4/5 )
= 10 + 1/5
= 10/1 + 1/5 = 50/5 + 1/5
                    = 49/5
                    = 9 4/5
Maaf banget kalo salah ya.............
