John bought a pack of 18 cards for $2.99. About how much did each card cost?

0.166

Step-by-step explanation:

Bought 18 cards for $2.99, so you can write it like this:

18 = 2.99

Since you want to find the value of one card, u could write that like this:

1 = x  (where x is the unknown value of 1 card)

To get from 18 to 1, you divide by 18, so to get to 2.99 to x you must divide by 18 as well.

So 2.99/18 = 0.166

therefore x = 0.166

So you can say that each card costs about 17 c

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
