Explanation:
#"the statement is " yprop1/x#
#"to convert to an equation multiply by k the constant of"#
#"variation"#
#rArry=kxx1/x=k/x#
#"to find k use the given condition for x and y"#
#x=25" when "y=5#
#y=k/xrArrk=xy=25xx5=125#
#"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=125/x)color(white)(2/2)|)))#
