Question

Is 13/52 in simplest form

Answer 1

I don't understand what's in 1, 2, 3........... 
Are you looking for their product in lowest form? 
if so.... then... 
1) 13/52 * 3/51 = 1/4 * 1/17 
= 1/68 answer 

2) 5/2 * 3/4 = 15/8 answer 

3) 1/15 * 30/9 = 1/15 * 10/3 
= 10/45 
= 2/9 answer 

Do you find converting to simplest form difficult? 
Lets try #3....... 
a number with 1 on its numerator is already on its simplest form such as 1/15...... with this all fraction must at least have numerator equal to 1 to say that it is in simplest form. 

30/9 is not on in simplest.... think of a # that if you divide on both numerator and denominator will give a whole #.....? Say you had in mind of 2 then try it, will it give a quotient of whole #? Lets try.... 30/2 = 15 which is whole #, and 9/2= 4.5 which is not... so 2 is wrong..... 
Lets try 3 as divisor...... 
30/3 = 10 which is whole # 
9/3 = 3 which is whole # then the lowest term is the quotient we got which is 10/3. This is the lowest bec we cant think anymore # which if use as divisor will give whole #.....  

another thing, multiplying two fraction on its lowest form doesn't mean it will give a product at its lowest..... just like in #3... 

Answer 2

Yes it is in its simplest form
