There are 16 pink jelly beans in a bag. The ratio of red to pink jelly beans in the bag is 3/4. Which proportion could NOT be used to find r, the number of red jelly beans in the bag
Let r----------> the number of red jelly beans in the bag p---------> the number of pink jelly beans in the bag
we know that r/p=3/4 p=16 so r/p=3/4--------> r/16=3/4-----> r=(3/4)*16-----> r=12
therefore
case A) 3/4=r/16-----> is correct, the proportion could be used to find r
case B) 16/r=4/3----> r=16/(4/3)----> r=16*3/4-----> r=12-----> is correct the proportion could be used to find r case C) 3/4=r/16-----> is correct, the proportion could be used to find r case D) 3/4=r/16-----> is correct, the proportion could be used to find r the answer is All proportions could be used to find r
