Question

what is direct and inverse proportion for class 8..explain it in simple language and how to deal it with... how can we identify whether it is direct or inverse

Answer 1

Two values are said to be in direct proportion when increase in one results in an increase in the other. Similarly, they are said to be in indirect proportion when the increase in one results in a decrease in the other.
for inverse proportion we can assume that
When one variable increases the other decreases in proportion so that the product is unchanged. If b is inversely proportional to a, the equation is of the form b = k/a (where k is a constant). Equation: y = 60/x. y is inversely proportional to x.
