Mark 3 and subtract 1 from each division
Step-by-step explanation:
Tara will mark the number line at point 3.
Then she will subtract 1 from 3 and mark at point 2.
Again subtracting 1 from 2 the next mark is at 1.
And the last mark is at 0.
The first mark at point 3 shows that the string is 3 feet long.
Now we need 1 foot divisions. So we subtract from 1 division from point 3 to get 1 foot long string. So we continue to get 3 equal parts each of 1 foot long by dividing the 3 feet long string into 3 equal divisions.
so the first piece is from 0-1 gives 1 foot long string
The 2nd piece is from 1-2 gives 1 foot long string
The 3rd piece is from 2-3 gives 1 foot long string
