Describe in detail how you would create a number line with the following points: 4, 1.25, the opposite of 3, and – (–2 fraction of one-half). Please be sure to describe on which tick marks each point is plotted and how many tick marks are between each integer. It may help for you to draw this number line by hand on a sheet of paper first.

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

ratio is 2 : 9

the answer is three

13.5 : 3
