One box of pencils has 500 pencils in it. Mike bought a box of pencils that has 3% more pencils in it. How many pencils were in the box that Mike bought?

Mike's box of pencils contains 515 pencils.

Step-by-step explanation:

3% of 500 is 15. If we add that onto the original 500, we get 515.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
