Question

what is direct proportion and inverse or indirect proportion

Priyanka Kedia · Accepted Answer

Direct
Proportion : Two quantities x and y are said to be
in Direct Proportion if they change in such a way that the ratio of
the two value of x is the same as the ratio of corresponding two
values of y Or, in simple way, when two quantities x and y are in
direct proportion, an increase in x causes a increase in y, while a
decrease in x causes a decrease in y
And,
Indirect
Proportion : Two quantities x and y are said to be
in Indirect Proportion if they change in such a way that the ratio
of the two value of x is the same as the inverse of the ratio of
corresponding two values of y Or, in simple way, when two
quantities x and y are in inverse proportion, an increase in x
causes a decrease in y, while a decrease in x causes an increase in
y
