 Question 222784: In the Dicovering Algebra: An Investigative approach, there is a question that says Find the value of the unknown number in each proportion? The problem is 52/91=42/s. So do i inverse it. Swich it up like this: 91/52=s/42? or keep it the same?Found 2 solutions by jim_thompson5910, stanbon:Answer by jim_thompson5910(28504)   (Show Source): You can put this solution on YOUR website! Start with the given equation. Multiply both sides by s Multiply both sides by 91 Multiply Divide both sides by 52 Reduce. So our answer is which in decimal form is Answer by stanbon(57250)   (Show Source): You can put this solution on YOUR website!The problem is 52/91=42/s. So do i inverse it. Switch it up like this: 91/52=s/42? or keep it the same? ------------------------------------- Invert both sides, as you have done: then solve for "s": 91/52 = s/42 ---- Multiply both sides by 42 to get: s = 42(91/52) s = 73.5 ================ Cheers, Stan H.
