There's no such commonly recognised thing as 'indirect proportion'. If you mean Inverse Proportion, this is when one quantity decreases as another increases by the same factor.
As an example, the time it takes to run 100 m is inversely proportional to the speed you run at - if you double your speed, it takes you half as long.
Many maths problems run along the lines of "If it takes three men four days to build a wall, how long will it take five men to build the same wall?". This is inverse proportion. As you increase the number of men by a factor of 5/3, you decrease the time taken by a factor of 5/3, so the answer here is 2.4 days.
I hope that helps!

How can you solve problems involving percents?
That would depend on the specific problem. The "rule of three" (i.e., solving proportions) can help for many standard problems; i.e., you consider a proportion, where the percentage has a denominator of 100. Here are some examples:1) What's 17% of 2000? The proportion to solve is: 17/100 = x/2000 2) 500 is what percentage of 2000? The proportion to solve is: x/100 = 500/2000 3) 500 is 10% of what number? The proportion to solve is: 500/x = 10/100
What is an equation that sets two fractions equal to each other called?
An equation that sets two fractions equal to each other is called a proportion. In a proportion, the cross products of the fractions are equal. For example, if you have the proportion ( \frac{a}{b} = \frac{c}{d} ), then ( ad = bc ). Proportions are commonly used in solving problems involving ratios and rates.
What is a ratio between two sets of measurements called?
A ratio between two sets of measurements is called a proportion. A proportion is a statement that two ratios are equal. It is often used to compare quantities or values in different contexts, such as in mathematics, science, and finance. The relationship between the two sets of measurements can be expressed using fractions or decimals.
