Question

Please explain the meaning of percentage with examples and how to solve them

Answer 1

The percent value is computed by multiplying the numeric value of the ratio by 100. ... To calculate apercentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them. For example, 50% of 40% is: ​⁵⁰⁄₁₀₀ × ​⁴⁰⁄₁₀₀ = 0.50 × 0.40 = 0.20 = ​²⁰⁄₁₀₀ = 20%.1. How to calculate percentage of a number. Use the percentage formula: P% * X = Y

1. Convert the problem to an equation using the percentage formula: P% * X = Y.
2. P is 10%, X is 150, so the equation is 10% * 150 = Y.
3. Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

In an election, candidate A got 75% of the total valid votes. If 15% of the total votes were declared invalid and the total numbers of votes is 560000, find the number of valid vote polled in favour of candidate.

Solution:

Total number of invalid votes = 15 % of 560000

= 15/100 × 560000

= 8400000/100

= 84000

Total number of valid votes 560000 – 84000 = 476000
