Penjelasan dengan langkah-langkah:

9] 2 1/2 x (1 2/5 + 1/10) x 1 1/2

= 5/2 x (1 4/10 + 1/10) x 3/2

= 15/4 x 1 5/10

= 15/4 x 1 1/2

= 15/4 x 3/2

= 45/8

= 5 5/8

10] (3 1/5 x 4/5) : (3 – 3/5)

= (16/5 x 4/5) : (15/5 – 3/5)

= 64/25 : 12/5

= 64/25 x 5/12

= 5/25 x 64/12

= 1/5 x 16/3

= 16/15

= 1 1/15
