Question

Two quantities 'a'and 'b'are said to be in direct variation if ________ remains constant

Answer 1

SOLUTION

TO FILL IN THE BLANK

Two quantities 'a' and 'b' are said to be in direct variation if ________ remains constant

EVALUATION

Here it is given that two quantities a and b are in direct variation

$\implies \sf{a \: \propto \: b}$

$\implies \sf{a \: = k b}$

$\displaystyle\implies \sf{ \frac{a}{b} \: = k }$

Where k is a non zero constant

So From above we see that in direct proportion, both a and b increases or decreases together in such a way that the ratio of their corresponding value remains constant

Hence Two quantities 'a' and 'b' are said to be in direct variation if

$\displaystyle \sf{ \boxed { \: \frac{a}{b} \: }}$ remains constant
