Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.P is 10%, X is 150, so the equation is 10% * 150 = Y.Convert the problem to an equation using the percentage formula: P% * X = Y.Read on to learn more about how to figure percentages. X and Y are numbers and P is the percentage: Let's explore the three basic percentage problems. The formulas below are all mathematical variations of this formula. You can think of the most basic as X/Y = P x 100. There are many formulas for percentage problems. Add or subtract a percentage from a number or solve the equations. Use percent formulas to figure out percentages and unknowns in equations.

What is the number of English speakers only? Solution 6 Example 6Ĩ5 percent of a company staff with 200 employees speak English and 70 percent of English speakers can speak French as well. there are situations where one percentage is calculated based on another percentage. However, we must be careful to make the distinction between independent events such as the situations given above and dependent events where one percentage determines the other, i.e. For example, if 35% of students in a class have scored 80 points or higher in an exam but only 12% of students have scored 90 points or higher, the percentage of students who scored 80 - 89 points is 35% - 12% = 23% of the class. The same is true for subtraction as well. For example, if 45% of a Spanish crew staff speak English and 37% of the same crew staff speak French, the percentage of staff who speak at least one foreign language is 45% + 37% = 82% of the staff. If the amounts expressed in percent are independent from each other, we can add or subtract the percentages as in addition or subtraction of real numbers. Yet, with percentages, we can do more types of additions and subtractions than with fractions or decimals. We can complete operations with percentages in the same way as we do with fractions and decimals.
