2 per X dikurang 2 per 5 = 1 per x ditambah 11 per 10

(2/x) - (2/5) = (1/x) + 11/10
(2/x) - (1/x) = 2/5 + 11/10
1/x = (4 + 11)/10
x = 10/15
x = 2/3

jawab!
2/× - 2/5 = 1/× + 11/10
2/× + 1/× = 11/10+2/5
3/× = 11/10 + 4/10
3/× = 14/10
di kali silang:
×(14) = 3(10)
14× = 30
× = 30/14
× = 2 2/14 (Dua, Dua per empat belas)
