Answer 1

1 - 1/9 = 8/9часть остаток
8/9*3/4=2/3часть от остатка
1/9 + 2/3 = 1/9+6/9=7/9часть материи израсходовали
1 - 7/9=2/9 часть материи осталась неизрасходованной

Answer 2

Calculating the Remaining Unspent Portion of the Material

To calculate the remaining unspent portion of the material, we can use the information provided.

Let's denote the original piece of material as M. According to the information given, 1/9 of M was spent, and 3/4 of the remaining portion was also spent.

To find the remaining unspent portion, we can use the following steps:

1. Calculate the portion spent from the original piece of material. 2. Calculate the remaining portion after the first expenditure. 3. Calculate the portion spent from the remaining portion. 4. Finally, calculate the remaining unspent portion.

Calculation Steps

1. Calculate the portion spent from the original piece of material: - 1/9 of the material was spent.

2. Calculate the remaining portion after the first expenditure: - After spending 1/9 of the material, the remaining portion is 8/9.

3. Calculate the portion spent from the remaining portion: - 3/4 of the remaining portion (8/9) was spent.

4. Calculate the remaining unspent portion: - To find the remaining unspent portion, we can calculate 1 - (1/9 + 3/4 * (8/9)).

Result

The remaining unspent portion of the original piece of material is 1/36.

This calculation shows that after spending 1/9 of the material and then 3/4 of the remaining portion, 1/36 of the original piece of material is left unspent.
