She needs 15 purple rectangles for 3 scarves

From the question, we have that 5/7 of the 7 rectangles will be purple

So, we have it that the number of purple rectangles in each scarve will be;


(5)/(7)*7\text{ = 5}

So in each scarve, there are 5 purple rectangles

In 3 scarves, the number of purple rectangles will be;


5\text{ }*3\text{ = 15}
