Answer 1

Пошаговое объяснение:

80р-90к-77р80к=1р30к

35,1м-19,408м-0,976м=14,716м

63см-4мм-9мм=61см7мм

Answer 2

To solve the given equations, we'll perform the subtraction operations indicated:

1. 80р. - 90к. - 77р. 80к.: Since we are working with different units (р. and к.), let's convert them to a common unit. Assuming р. represents rubles and к. represents kopeks, we can convert them to a common unit of kopeks.

   80р. = 80 * 100к. = 8000к. 77р. 80к. = 77 * 100к. + 80к. = 7780к.

   Now we can perform the subtraction: 8000к. - 9000к. - 7780к. = -8780к.

   Therefore, 80р. - 90к. - 77р. 80к. equals -8780к.

2. 35.1м - 19.408м - 0.976м: Since we are working with the same unit (meters), we can directly subtract the given values:

   35.1м - 19.408м - 0.976м = 14.692м - 0.976м = 13.716м.

   Therefore, 35.1м - 19.408м - 0.976м equals 13.716м.

3. 63см - 4мм - 9мм: Since we are working with different units (см and мм), let's convert them to a common unit. We can convert мм to см by dividing by 10.

   4мм = 4 / 10см = 0.4см. 9мм = 9 / 10см = 0.9см.

   Now we can perform the subtraction: 63см - 0.4см - 0.9см = 62.6см - 0.9см = 61.7см.

   Therefore, 63см - 4мм - 9мм equals 61.7см.
