Answer:
hello thereeeee
ans is 23.5
Step-by-step explanation:
so lets start
first of all remove decimal of divisor 1.1/25.85 multiplying by 10 
11/258.5
now first multiply by 2 
now we get 22 and subtract with 25 => 25-22 = 3 
so left is 
38 
now 11*3 = 33 
so now by 3 
38-33= 5 
bringing another 5 down
we get 55 
now quotient is 23. something ( as we bought .5 down) 
and now 11*5 = 55 
so 
23.5 is answer
