What are the signs for an inequality (in words and symbols)?

What is absolute value?
The distance of a number from 0.
Plot 3/4 and -.25 on a number line and their opposites.
Plot correctly.
Simplify the fractions, using GCF:
4/12
7/42
11/99
45/54
4/12 - 3/4
7/42 - 1/6
11/99 - 1/11
45/54 - 5/6
How to convert a decimal to a fraction? Give an example.
Based on the place of the last decimal, you put the decimal over the place value.
Ex: .65 - 65/100 and .7 - 7/10
Are absolute value and opposite numbers the same thing? Why or why not?
No, because absolute is the distance from 0, regardless of negative and positive numbers. Opposite numbers are the number on the other side of 0 with equal distance from 0.
Create a number line -2/3, 1/3, 1, -2
Correctly create plot.
What is the least common denominator for 7/12, 5/8, and 1/6?
