To work out the cost of 9 pens, you can first divide the cost of 12 pens by 12, which gives you the cost of one pen. Then, multiply that by 9. In this case, 6.36 ÷ 12 = 0.53 per pen. So, 0.53 × 9 = 4.77 for 9 pens. If you ever need quick help with calculations like this, https://calculatoradam.com/ has a wide range of tools to make math and finance problems a breeze!
