I'm having trouble with Fractions & Decimals on a Number Line

So my daughter is working with Fractions & Decimals on a Number Line and I'm totally confused and need help in explaining it to her. I will list the following problems below. I would greatly appreciate the help.

 

 

Name the mixed number that is shown with a dot on the number line. Express your answer in simplest form.

 

strong>I----I----I----I----I----I----I----I----I----I----I---*I----I----I----I >

   0       +1       +2      +3     +4       +5      +6      +7

 

I'm using the star to represent the dot in the book.

Hi there,

Looking at your example, there are 10 small lines in between each number. Those lines each stand for 1/10 of a whole. There are 10 lines in between each number. Think about money...10 dimes make a dollar (or a whole). So looking at the number line think of the whole numbers as dollars and the little ones as dimes ( use real money with your child if you have to).  It looks like you dot would translate to $6.90 and that translates to 6 9/10 ( 9 dimes out of a dollar). Hope that helps!

Question: Why is this a mathematical limerick?

( (12 + 144 + 20 + 3 Sqrt[4]) / 7 ) + 5*11 = 92 + 0 .

Answer:

A dozen, a gross, and a score,
plus three times the square root of four, divided by seven, plus five times eleven, is nine squared and not a bit more.

---Jon Saxton (math textbook author)
