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?
2 answers:
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 ≈ <span>55.09
55.09 toothpicks per stair.
55.09 </span>× 55 = <span>3029.95
So, to build a 55-step stair case Ann will need</span> ABOUT 3029.95 tooth <span>picks.

160. This is because u take the total(240) divide it by 18 and multiply by 12.
however, you can also simplifiy the fraction (12/18) into (2/3) and divide by the bottom denominator (3) and multiply by the top numerator. ;)
