Multiply 0.1 by 400 to get 40. This is how you find 10% of 400 without using proportion.
100/62 is the appropriate proportion.
To find a percent.
Part = Base*Percent/100Proportion = Part/Base = (Base*Percent/100)*Base = Percent/100.
you set up a proportion and cross multiply then divide
Both percent proportion and percent equation are methods used to solve problems involving percentages. The percent proportion expresses the relationship between the part, whole, and percent as a fraction: ( \frac{\text{part}}{\text{whole}} = \frac{\text{percent}}{100} ). The percent equation, on the other hand, is formulated as ( \text{part} = \text{percent} \times \text{whole} ). While they are different in form, both approaches ultimately help find the same values in percentage-related problems.

to find percents using a proportion u first put the percent over 100 and put the whole number (number that you are tyring to find the percent of) over one. than you multiply those Example- 29 500 ___ times ____ 100 1 than you would multiply them
A simple tool to remember is: IS over OF equals percent over 100.If we put this into a proportion, we get:IS/OF = percent/100.Just put all percent problems into this format, and solve the proportion.Example: 12.5 IS what percent OF 75?Or,12.5 IS | what percent | OF 75?Just put these numbers into the proportion: (We will use x for the percent, as that is the unknown we are solving for)12.5/75 = x/100.Then solve by cross multiplying:75x = 1250.Then divide by 75:x = 1250/75,x = 16 2/3 %
You can use the equivalent form of the percent proportion, which is expressed as ( \text{part} = \text{percent} \times \text{whole} ), to solve percent problems by identifying the part (the amount you want to find), the percent (the percentage given), and the whole (the total amount). By rearranging the formula, you can solve for the unknown variable. For example, if you need to find 20% of 50, you can calculate it as ( \text{part} = 0.20 \times 50 ), leading to the solution of 10.
To solve ratio, proportion, and percent problems, first convert the problem into a fraction if necessary. For percentages, express the percent as a decimal (e.g., 25% as 0.25) and then apply it to the relevant quantity. Use cross-multiplication for proportions to find unknown values, and remember that the formula for percent is: Percent = (Part/Whole) × 100. Finally, ensure to simplify your answers where possible for clarity.
