Question

THIS IS A GRADE 8 WORD PROMBLEM. FOR THE QUESTION DO YOU NEED 1 LETTER OR 2.

Answer 1

I would answer this question like this...

• first, how many questions are they asking?  1 
• How many planetariums are there in Canada?
• To figure this first what do we know? 
• We know 1/6 of Canada's planetariums are in Halifax. 
• We know that there are 2 planetariums in Halifax. 
• So the variable we don't know is how many planetariums there are in Canada.
• The 2 planetariums in Halifax is 1/6 of the total planetariums and our equation needs to use this information.

1. 2=x/6 which would mean we need to multiply by 6 to get rid of the fraction. 
2. x/6 * 6 = X. 
3. Then whatever you do on one side you do on the other 2 * 6 = 12. 
4. 12 = X 
5. So what does 12 mean?  What was our question? 
6. How many planetariums are there in Canada?  Answer = 12. 
7. Let's test our answer  2 = 12/6 
1. How many times does 6 go into 12??  2 
2. 2=2  Correct...
3. 2 is 1/6 of the total planetariums. 
4. Is 2 = 1/6 to 12?  2+2+2+2+2+2 = 12  2 is in fact 1/6 of 12.

Answer 2

x = total number of planetariums

 

x/6 are in Halifax.  The are 2 in Halifax.

 

x/6 = 2

 

x = 6(2) = 12
