May I know by drawing the model for R of having 2 small units of 15 stamps each, which facts of the question is it trying to establish?[/quote]it is \"draw model for R having 2 small units of 15 stamps each MORE THAN W\".
1st, draw the model for R having 2 small units (of 15 stamps each) more than W.The Right Equation:
[quote=\"doraemo\"]pls help
(1)\tW and R collect stamps. If R gives W 15 stamps, he will have the same number of stamps as W. If W gives R 15 stamps, he will have ½ as many stamps as R. How many stamps does each of them have?

means W is a large unit, & R is two small units MORE THAN it. -
