A cake factory used 7 4/5 to make ten cakes how many cakes make one

Question

It is not a question you guys super duper need to answer but I would like some help on trying to figure it out.

Answer 1

7 4/5 = 39/5

 

You need 1/10 of 39/5

 

(1/10)(39/5) = 39/50

 

Or, a ratio.

 

(39/5)/10 = x/1

 

Cross multiply.

 

10x = 39/5

x = 39/50
