4per5-2per4+(2per3×1 1per 2=.......tlong jwb yaaa

4/5 - 2/4 + ( 2/3 × 1 1/2 )
= 4/5 - 2/4 + ( 2/3 × 3/2 )
= 4/5 - 2/4 + 1
= 16/20 - 10/20 + 20/20
= 26/20 => masing2 dibagi 2
= 13/10
= 1 3/10

Jawabannya:

4/5 - 2/4 + (2/3 × 1 1/2)
= 4/5 - 2/4 + (2/3 × 3/2)
= 4/5 - 2/4 + (6/6)
= 4/5 - 2/4 + 1
= 16/20 - 10/20 + 20/20
= 6/20+20/20
= 26/20
= 13/10
Atau
= 1,3
