Ann made a 33-step staircase using 1818 toothpicks as shown in the figure. How many toothpicks does she need to add to complete a 55-step staircase?

You would take 1818÷33=55.09

55.09 is how many toothpicks it took for each step made

Then you would take 55.09×55=3029.95

You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up

To answer this we will do the following:-

1818 ÷ 33 ≈ 55.09
55.09 toothpicks per stair. 

55.09 × 55 = 3029.95

So, to build a 55-step stair case Ann will need ABOUT 3029.95 tooth picks.

Hope I helped ya!!
