There are 10 triangles and 4 circles. What is the simplest ratio of circles to total shapes?

5:2

Step-by-step explanation:

Well, you are going to find a number they both divide by in this case it is 2

10/2=5

4/2=2

Now when rewriting your numbers make sure to put what comes first first

5:2

5 and 2 can not be divided evenly anymore so your final answer is 5:2

Hope this helped!

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
