Question

От ленты длиной 15 дм отрезали кусок длиной дм. Какой длиной лента осталось?

Answer 1

15 дм. - 1 дм. = 14 дм.

Answer 2

Calculating the Remaining Length of the Ribbon

To calculate the remaining length of the ribbon, we can use the following formula:

Remaining length = Total length - Length of the piece cut

Given: - Total length of the ribbon = 15 dm - Length of the piece cut = 4 dm

Calculation

Using the formula, we can calculate the remaining length of the ribbon:

Remaining length = 15 dm - 4 dm = 11 dm

Therefore, the length of the ribbon that remains is 11 dm.
