Answer:
Part 1) Trinity 233/407
Part 2) Jason 174/407
Explanation:
we know that
Trinity sold $2,330 and Jason sold $1,740
so
step 1
Find out the total sales
The total sales is equal to Trinity's sales plus Jason's sales
so
$2,330+$1,740=$4,070
step 2
The fraction of total sales that Trinity sold is equal to divide the sales of Trinity by the total sales
2,330/4,070
Simplify
233/407
step 3
The fraction of total sales that Jason sold is equal to divide the sales of Jason by the total sales
1,740/4,070
Simplify
174/407
