Answer 2

To subtract 9 rubles and 90 kopeks from 12 rubles and 85 kopeks, you can use the following method:

1. Convert the kopeks to rubles (1 ruble = 100 kopeks).
2. Subtract the rubles and kopeks separately.
3. If the result has a negative value for the kopeks, borrow 1 ruble and adjust the kopeks accordingly.

Let's do the calculations:

1. Convert kopeks to rubles: 85 kopeks = 85 / 100 rubles = 0.85 rubles

2. Subtract the rubles and kopeks separately: 12 rubles - 9 rubles = 3 rubles 0.85 rubles - 0.90 rubles = -0.05 rubles

3. Adjust the result: Since the kopeks have a negative value, we need to borrow 1 ruble and add 100 kopeks to the kopeks value. 3 rubles - 1 ruble = 2 rubles 100 kopeks - 5 kopeks = 95 kopeks

So, the result of the subtraction is 2 rubles and 95 kopeks (2.95 rubles).
