Four questions.
The first step in calculating the percent of numbers is to change the percent to a decimal. When you see the word "of" in word problems, that signals multiplication, so take the decimal and multiply by the number.
The circumference is directly proportional to the radius. So increasing the radius by 50% causes the circumference to also increase by 50%.
Three mathematical concepts are inherent to solving proportional equations. The first is algebraic operations, and using the same process on both sides of the parenthesis' expression. Other algebraic skills include cross-multiplication, division, and simplification of quantities. The second is an understanding of percent's and fractions, which can help visualize the proportions.
A percent is a proportion with the denominator equalling 100.
If two quantities are directly proportional, when one quantity increases by 10 percent, the other quantity will also increase by 10 percent. This means that the relationship between the two quantities remains consistent as they change by the same proportion.

This is a fixed rate (proportional) tax, not a regressive tax.
.025 Keep in mind one percent = .01, that makes it easier to solve questions involving %'s!
They are similar because their sides are proportional and their angles are equal.
The density of a cell suspension is expressed as absorbance (A) rather than percent T, since A is directly proportional to the concentration of suspended cells, whereas percent T is inversely proportional to the concentration of suspended cells. Therefore, as the turbidity of a culture increases, the A increases and percent T decreases, indicating growth of the cell population in the culture.

The major types of stoichiometry problems involve calculating the quantities of reactants and products in a chemical reaction. This includes determining mole ratios, mass-mass relationships, limiting reactants, and percent yield. Other common types of problems include volume-volumetric relationships and stoichiometry involving gases.
