Answer: A dot at 1 4/6, and a dot at 2 3/6
Step-by-step explanation: This number line seems to be split up into 6ths, with 6 intervals between each number. All you would need to do here is to simply convert the fractions into sixths, which you can do by seeing how much you'd need to multiply the denominator by and multiplying both numerator and denominator by that number. Let's try it out. 1 2/3. You need to multiply 3 by 2 to get six, so let's multiply both the numerator AND denominator by 2. 2x2=4, 3x2=6. That makes it 1 4/6, repeat with the other number, and you get 2 3/6. I hope this helps!
