Question

!!!!срочно!!!! Наташе родители дали 5 плиток шоколада, среди которых был черный и молочный. Черный шоколад Наташа не любила и поэтому 2 его плитки она подарила своей подруге Ире. После этого в оставшемся у Наташи шоколаде доля молочного составила 100%. А сколько процентов составляла доля молочного шоколада до того, как Наташа сделала свой подарок Ире?

Answer 1

2/5* 100% = 40% - доля черного шоколада изначально 
100% - 40% = 60% - доля молочного шоколада

Answer 2

5 плиток- 100%
1 плитка-100:5=20%
5-2=3 плитки молочного шоколада
20*3=60%
ответ: 60%

Answer 3

Calculation of the Percentage of Milk Chocolate

To calculate the percentage of milk chocolate in the remaining chocolate that Natasha had before giving two pieces to her friend Ira, we need to consider the information provided.

Natasha's parents gave her 5 chocolate bars, which included both black and milk chocolate. Natasha didn't like black chocolate, so she gave 2 of the black chocolate bars to her friend Ira. After this, the remaining chocolate consisted only of milk chocolate.

To find the percentage of milk chocolate before Natasha gave the chocolate to Ira, we need to determine the proportion of milk chocolate in the original 5 bars.

Let's assume that the original 5 bars consisted of x black chocolate bars and y milk chocolate bars. Since Natasha gave 2 black chocolate bars to Ira, the remaining chocolate consisted of (x-2) black chocolate bars and y milk chocolate bars.

According to the information provided, the remaining chocolate consisted only of milk chocolate, which means that (x-2) black chocolate bars = 0. Therefore, x = 2.

Since the original 5 bars consisted of 2 black chocolate bars and y milk chocolate bars, the percentage of milk chocolate can be calculated as:

Percentage of milk chocolate = (y / 5) * 100

Since x = 2, the percentage of milk chocolate can be simplified to:

Percentage of milk chocolate = (y / (2 + y)) * 100

Unfortunately, the exact values of x and y are not provided in the question, so we cannot determine the specific percentage of milk chocolate without this information.

If you have the values of x and y, please provide them so that we can calculate the percentage of milk chocolate accurately.
