Answer:
The ratio that exist between this three elements are 25 : 19 : 13. 
Step-by-step explanation:
Ratio compares one thing to another. Ratios indicate the comparison of the size of a number to another . One trick about ratio is that you can multiply or divide the ratios by same number. For example the ratio of boy to girls can be represented as 3 : 4. If you multiply the ratios by 2 you will get the ratio 6 : 8 and it still represent the same ratios of boys to girls. Ratios can be written as a fraction for example 3/4 for our example. 
The cost of the unit is made up of $6.25 , $4.75 and $3.25. 
$6.25  $4.75  $3.25 . Let us multiply by 100 to remove the decimals.
625 : 475 : 325 . Now let simplify the ratios by dividing through by 25. 
625/25 : 475/25 : 325/25 . The simplest ratios can be written as follows
The ratios are 25 : 19 : 13.

Answer:
1 10/12
Step-by-step explanation:
Take the fractions and get them to the same bottom number, 12.  So it would be 5 4/12 -  3 6/12. 
Take 1 away from 5 to get 4 and the one you pulled would be 12/12(also equal to 1).  4  16/12 - 3  6/12 would be 1  10/12
