Well first you would start by setting up with a proportion.
In total, the girls paid $54+$22= $76
Thus 1 sister contributed $54/$76=x/100
The other sister contributed $22/$76=x/76
For each proportion, cross-multiply and simplify to get the percentage. The percentage will be the x

You and your sister bought your mom a gift.
You paid $54 and your sister paid $22.
Because 54 + 22 = $76, the gift cost a total of $76.

To figure out what percentage each sister paid, you divide what they paid by the total cost.

Thus, because you paid $54, the percentage of the gift that you bought is 54/76 ≈ 0.71 = 71%

Therefore, because your sister paid $22, the percentage of the gift that she bought is 22/76 ≈ 0.29 = 29%

You bought 71% of the gift and your sister bought 29% of the gift.

Sammy and David were selling water bottles to raise money for new football uniforms famous or 5 water bottles for every 3 water
ANTONII [103]
In the given question, we come to know that Sammy sold 5 bottles for every 3 water bottles sold by David. In this case we get the ratio as 5:3
Now this ratio indicates that the total number of bottles can be divided into 8 parts for finding out a single part. the total number of water bottles that are sold by Sammy and David together are 160.
Now on dividing this total number of bottles by 8 we get the 20 as one part.
The,
Number of Bottles sold by Sammy = 5 * 20
                                                         = 100
Number of bottles sold by David = 3 * 20
                                                   = 60
So Sammy sold 100 water bottles and David sold 60 water bottles from the total of 160 water bottles.
