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.
100/62 is the appropriate proportion.
To find a percent.

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 %
