If one square takes 16.4 cm of wire, this means that to form 25 identical squares you need 25(16.4) cm of wire = 410 cm 

To convert this to m you just need to divide it by 100 because there are 100 cm in one meter = 4.1 m 

Therefore your final answer is: You need 4.1 m of wire to form 25 squares, each with a perimeter of 16.4 cm.

Claire said that 10/15 of her CDs are country music. Which statement could be true based upon this relationship?
never [62]

Answer:

C. Claire has 10 country CDs and 5 Jazz CDs

Step-by-step explanation:

\dfrac{10}{15} means that 10 out of 15. So we can assume that in total she has 15 CDs and 10 of them are Country and the other is Jazz.

This would rule out choice D.

If we reduce this fraction then we would have:

\dfrac{10}{15} = \dfrac{2}{3}

This means that two-thirds of her CDs are country music. So this would rule out A and B choices.

Now C is correct because 10 country plus 5 Jazz is equal to 15 CDs. So we have the correct total.

The answer is C.
