What is the missing number (?) on the number line below?

000???111

Step-by-step solution

Let's first count how many points, including the number 1, there are on the number line.

Since there are 11 in total, we'll define the 0 point as the following fraction:

011 \frac{0}{11}

We will also define 1 as the following fraction:

1111 \frac{11}{11}

Now let's fill in each point on the sequence to discover what our missing number is:

Final Answer

1011 \frac{10}{11}

Key Points to Remember

Essential concepts to master this topic
  • Counting Strategy: Count total divisions between known points to find denominator
  • Position Method: From 0 to ?, there are 10 equal steps out of 11 total
  • Verification: Check that 1011 \frac{10}{11} is close to 1 but less than 1 ✓

Common Mistakes

Avoid these frequent errors
  • Miscounting the number of divisions on the number line
    Don't count only the visible marks or forget to include the endpoint = wrong denominator! This leads to fractions like 9/10 instead of the correct answer. Always count all equal divisions from 0 to 1, including both endpoints.

FAQ

Everything you need to know about this question

How do I know what the denominator should be?

+

Count the total number of equal divisions between 0 and 1. In this problem, there are 11 equal parts total, so the denominator is 11.

Why is the answer 10/11 and not 9/11?

+

The question mark is at the 10th division point from 0. Count carefully: 0 is the starting point, then count each mark until you reach the ?. You should count 10 steps.

How can I check if my fraction is in the right position?

+

Ask yourself: Is my fraction close to 1 but still less than 1? Since 1011 \frac{10}{11} is very close to 1111=1 \frac{11}{11} = 1 , this makes sense for the position shown.

What if I can't see all the marks clearly?

+

Look for the pattern of equal spacing. Count the marks you can see clearly, then use that spacing to determine the total number of divisions between 0 and 1.

Do I need to simplify 10/11?

+

No! 1011 \frac{10}{11} is already in simplest form because 10 and 11 share no common factors other than 1.
