Question

В таблице размером 10× 12 закрашены 30%. сколько всего клеток закрашено ?

Answer 1

S=120 120÷100=1.2 (один %)
1%=1.2
30×1.2=36 клеток

Answer 2

To find out how many cells are shaded, you can simply calculate 30% of the total number of cells in the table.

A 10x12 table has a total of 10 * 12 = 120 cells.

To find 30% of 120, you can multiply 120 by 0.3 (which represents 30% as a decimal):

30% of 120 = 0.3 * 120 = 36

So, 36 cells are shaded in the 10x12 table.
