Answer 2

To solve the missing value, we can use proportions. Let's find the missing percentage.

Let's take 78% as 100%, and then calculate the equivalent of 21%, and do the same for 3.5%.

1. 78% - 21% = 57%

So, 78% is 100% and 21% is 57%.

2. Now, let's find the equivalent of 1%: 57% ÷ 21 = 2.71428571 (approximately)

So, 1% is approximately 2.71428571%.

3. Finally, let's find the missing percentage by multiplying 100 by 2.71428571:

   100 × 2.71428571 ≈ 271.428571%

Therefore, 100% - ? ≈ 271.428571%

The missing value is approximately 271.428571%.
