Question

Ollvia is making scarves. Each scarf will have 7 rectangles, and of the rectangles will be purple. How many purple rectangles does she need for 3 scarves? Olivia needs purple rectangles

Answer 1

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}`
