Answer 2

To calculate the given expressions:

1. 18 руб. 78 коп. * 1: To perform this calculation, we need to convert kopeks (коп.) to rubles (руб.) since they represent a fraction of a ruble. There are 100 kopeks in 1 ruble.

18 руб. 78 коп. = 18 rubles + 78 kopeks = 18 + (78 / 100) rubles = 18.78 rubles

Now, we can proceed with the multiplication:

18.78 rubles * 1 = 18.78 rubles

So, 18 руб. 78 коп. * 1 = 18.78 rubles.

2. 2 т 273 кг * 9: To multiply these quantities, we need to first convert 2 tons (т) to kilograms (кг) since 1 ton is equal to 1000 kilograms.

2 т = 2 * 1000 кг = 2000 кг

Now, we can proceed with the multiplication:

2000 кг * 9 = 18,000 кг

So, 2 т 273 кг * 9 = 18,000 кг.
