8050 is the answer to "what does 805 tens="
Answer:
5:1 cm
Step-by-step explanation:
Let's look at the ratio in fraction form, since ratios are easier to think about in this mathematical way:

Now we have a fraction which is easier to work with. We can look for a common factor of 25 and 5 and then factor it out to find the lowest terms of our ratio and the simplified version of the fraction. One common factor of 25 and 5 that I can think of is 5 itself. So, let's divide both sides by 5.
÷
= 
Does that make sense? 25 divided by 5 is 5, and 5 divided by 5 is 1. So the simplified version of the fraction is
, and the lowest terms of the ratio 25:5 cm is 5:1 cm.
Hopefully that makes sense! If you need more help or any of that was confusing or difficult to understand, let me know. :)
A strategy is making a vertical number line or rounding the numbers
The Standard deviation could only be zero if all the data points in your set are equal. If all data points are equal, there is no deviation.
