Answer 2

Составим и решим пропорцию (главное правило пропорции: произведение крайних членов равно произведению средних; умножаем крест-накрест):

5 - 7%

x - 100%

7x = 5·100

7x = 500

x = 500:7

x = 71,42.

Значит, 100% - число 71,42.

Ответ: 71,42

Answer 3

To find the number that corresponds to 100%, we need to use simple proportionality.

Let's represent the unknown number as "x". We know that 5 is 7% of "x". Mathematically, we can write this as:

5 = 0.07 * x

Now, to find "x," we need to divide both sides by 0.07:

x = 5 / 0.07

Now, calculate:

x ≈ 71.43

So, the number you're looking for is approximately 71.43 when considering 100%.
