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.

inessss [21]

Answer:

Area = 10 1/9 meters squared

Step-by-step explanation:

mixed number to improper fraction:

4 2/3 meters = 14/3 meters

2 1/6 meters = 13/6 meters

Area = length times width:

Area = (14/3) x (13/6)

        = 182/18

Simplify fraction:

182/18 = 91/9

improper fraction to mixed number:

91/9 = 10 1/9 meters

AREA = 10 1/9 meters
