Question

За три дня на шахте добыли 2 436,86 т угля. За первый день добыча составляла 827,48 т, а за второй-на 59,59 т меньше, чем за первый. Сколько тонн угля добыли за третий день?

Answer 1

1) 827,48-59,59= 767,89 (т) - 2-й день
2) 827,48+767,89=1 595,37 (т)- разом 1 і 2 
3) 2 436,86-1 595,37 = 841, 49 (т)- третій 

Answer 2

1)827.48-59.59=768.19 (т)-за 2 день
2)2436.86-768.19-827.48=841.19 (т)-за 3 день

Answer 3

Calculating Coal Production

To calculate the coal production for the third day, we can use the information provided.

Given: - Total coal production in three days = 2,436.86 t - Coal production on the first day = 827.48 t - Coal production on the second day = 827.48 t - 59.59 t

Calculation

We can calculate the coal production on the third day by subtracting the total production of the first two days from the total production in three days.

Coal production on the third day = Total production in three days - (Coal production on the first day + Coal production on the second day)

Coal production on the third day = 2,436.86 t - (827.48 t + (827.48 t - 59.59 t))

Coal production on the third day = 2,436.86 t - (827.48 t + 767.89 t)

Coal production on the third day = 2,436.86 t - 1,595.37 t

Coal production on the third day = 841.49 t

Therefore, 841.49 tons of coal were produced on the third day.

I have used the given information to calculate the coal production for the third day.
