What is the chance of snow for a few days in a row in a percentage?

I don’t know, you tell me, please start with something easy

Could you tell me what is the chance of snow for the next few days in a row in a fraction?

I think so

What about in a decimal?

Maybe so

If you can tell me the chance of getting snow for the next few days in a row in a fraction and a decimal, you can tell me in a percentage,

Did you know things in math are related?

How so?

Here is my example- Percentages are out of 100, decimals can be out of 100 and fractions can be out of 100.

These all happen to be out of 100 which makes them all related. If you know one, you know them all

This time, do you think you could tell me the chance of getting snow for the next few days in a row in a percentage?

a)5+11=16

b)-5+(-11)=-16

c)-5-(-11)=6

d)5-11=-6

e)5-(-11)=16

f)-5-11=-16

g)-5+11=6

**Questions:**

Explain which statements are equivalent and why.

Question A and E are equivalent because they are the same question 5+11=16 and in E all you do is make the subtraction signs plus signs. Question B and F are equivalent because again they are asking the same thing which is -5-11=-16. Question C and G are equivalent which is -5+11=6, this question is the same thing as A and E where the subtraction signs become plus signs so the question becomes the same which makes the answer the same.

What did you learn by completing this activity?

I learned that counters could help you count and figure out problems easier sometimes. I also learned that equations and questions could look different but be the same.
