The Answer:
70% of 90 is 63.

Calculating 70% of 90:
To calculate 70% of 90, we can use the formula:
Percentage = (Part / Whole) x 100
In this case, the part is 70% and the whole is 90.
Percentage = (70 / 90) x 100
Percentage = 0.7777… x 100
Percentage = 77.77…
Therefore, 70% of 90 is 77.77… or 63 when rounded to the nearest whole number.
Applications of 70%:
The concept of 70% finds applications in various fields, including:
-
Finance and Economics:
- The 70-30 rule, where 70% of a portfolio is allocated to stocks and 30% to bonds.
- The 70% of GDP rule, which suggests that 70% of a country’s GDP is consumed by households.
-
Healthcare:
- The 70% alcohol rule, which states that 70% ethyl alcohol is the optimal concentration for killing bacteria.
- The 70% rule of thumb, which suggests that 70% of people have a normal range of blood pressure.
-
Education:
- The 70% rule of learning, where 70% of learning occurs through experience and practice.
-
Engineering:
- The 70% rule of efficiency, which suggests that a system’s efficiency rarely exceeds 70%.
