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;

$\frac{5}{7}\times7\text{ = 5}$

So in each scarve, there are 5 purple rectangles

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

$5\text{ }\times3\text{ = 15}$
