Question

Roberta is going to make a number line from 0 to 4 by one fourths. not including the mark for zero, how many marks should she draw?

Answer 1

She needs to draw four marks.

Explanation:

If Roberta is going to make a number line from 0 to 4 by one fourths, she needs to wonder, how many one-fourths are from 0 to 4.

So, there are 4 one-fourths form 0 to 4.

This means she needs to draw 4 marks withouth including the zero, because with the zero would be 5 marks.

The image attached shows the number of marks needed.

Therefore, without including the zero mark, she needs to draw four marks.

Answer 2

Dividing 4 by 1/4 will give us 16. There are 16 marks therefore from 0 to 4. This is true even if the number 0 is not placed with any marks. That is 1/4, 1/2, 3/4, 1 for the first number. This is repeatedly done up to number 4. Thus, giving us 16 marks.
