Percent yield is simply the actual yield (the mass of resultant) divided by the theoretical yield (the most that can be attained). Therefore, the possibility of having a percent yield greater than 100 is impossible unless an error is made during the procedure.
Know MoreTheoretical yield remains in the denominator while the actual mass of your product stays in the numerator. This can be thought of as "how much you attained" divided by "how much you could have attained." This thought process may help to point out an error in the equation that results in a percent yield greater than 100.

To multiply fractions, simply multiply the numerators and denominators together. To divide fractions, multiply the first fraction by the inverse of the second fraction.

Full Answer >To multiply polynomial fractions, also called rational expressions, break down the given problem into individual polynomials, and factor them. Once the polynomials are factored, cancel any like factors, and simplify the remainder. Do not make the mistake of canceling similar terms between the fractions.
Full Answer >To divide a whole number by a decimal number, move the decimal point to the right in both numbers until the decimal is a whole number. Then, divide the numbers normally.
Full Answer >Some simple way kids can figure out percentages are to relate basic fraction with percentages or use grid paper. Grid paper that is 10 by10 is useful for teaching younger students that a percentage is given as parts per 100. For example, using grid paper or sheet, teachers can show that 10 percent is 10 squares on the grid sheet that contain 100 squares, or 10 per 100; once students master finding percentages with this technique, they can move on to equating basic percentages like 10 percent, 25 percent and 50 percent with their corresponding fractions.
