My 8 year old sister needs on this question. roberta is going to make a number line from 0 to 4 by 1/4s. not including the mark for 0, how many marks should she draw? a. 8 b. 12 c. 16 d. 20

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.

The answer will be 16. There are 4 1/4s on a ruler. Then you do 4 • 4 which equals 16

No because if you do the higher number minus the lower number you will get a positive. if you do it the other way around you will get a negative number
