Drawing the model for this question will be difficult because we are not sure of how many units of marbles each of them had at first. This is why we start from the end of the story.
To draw the model from the end, we understand the story from the last part.
If you need me to draw the model, let me know, but not for the time being.
(At the end)
S : R
9 : 9
(Before Sharon gave Ryan 40% of her marbles)
S : R
15 : 3
(Before Ryan gave Sharon 2/5 of his marbles)
S : R
13 : 5
We assigned 9 : 9 as the final number so that we will deal with whole numbers for the units - it will look a little strange to have a decimal number of units.
