Math Easy Solutions - Home FacebookMath Easy Solutions August 3 · In # MESScience 2, I go over Part 1 of an obscure concept called vortex math or vortex based mathematics and which involves me doing extensive deep-dive into modular arithmetic and number theory to understand the resulting patterns. Percentage (How to Calculate, Formula and Tricks)How to calculate the percentage of a number? To calculate the percentage of a number, we need to use a different formula such as:P% of Number = X. where X is the required percentage. If we remove the % sign, then we need to e the above formulas as; P/100 * Number = X. Example:Calculate 10% of 80. Let 10% of 80 = X. 10/100 * 80 = X. X = 8
Convert the problem to an equation using the percentage formula:P% * X = Y. P is 10%, X is 150, so the equation is 10% * 150 = Y. Convert 10% to a decimal by removing the percent sign and dividing by 100:10/100 = 0.10. Substitute 0.10 for 10% in the equation:10% * 150 = Y becomes 0.10 * 150 = Y.
