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 = 9^{2} + 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)

The Math Behind the Fact:
