Multiply the cross products, and see if they are equal. If they are equal, the proportion is true. If they are unequal, the proportion is false.
A ratio is simply a comparison between 2 numbers. Example- 4:3 A proportion is 2 fractions equal to each other or "proportionate".
The ratios a/b and c/d form a proportion is if their simplified forms are the same, or equivalently, if a*d = b*c
You tell by knowing the material and studying. If you have kept up with your work, it will be pretty obvious that the answer is true or false unless you have a sneaky teacher who makes really hard test questions.
a/b = c/d if and only if a*d = b*c.

False. In a mixture, the constituents are not present in a fixed proportion; they can vary in amounts. This distinguishes mixtures from compounds, where elements are combined in specific ratios. Mixtures can be homogeneous or heterogeneous, depending on how well the components are mixed.
There is a 95% probability that the true population proportion lies within the confidence interval.
