2 1per2 - 1per4 dikali 2 2per5 : 3per5 + 2per5

21/2 - 1/4 × 12/5 + 2/5
21/2 - 12/20 + 2/5
210/20 - 12/20 + 8/20
206/20 = 10 6/20 = 10 3/10
Semoga membantu

jawab,

= 2 1/2 - 1/4 × 2 2/5 : 3/5 + 2/5

= 2 1/2 - ( 1/4 × 2 2/5 : 3/5 ) + 2/5

= 5/2 - ( 1/4 × 12/5 × 5/3 ) + 2/5

= 5/2 - ( 1 ) + 2/5

= 25/10 - 10/10 + 4/10

= 11/10

=10 1/10

10 1 per 10

semoga membantu yah ehhehe
