Answer: $7700
Explanation:
Let x represent the amount of money given to the three friends to share.
Keisha, Tracey, and Kerry-Ann shared the money in the ratio 5:7:9 respectively.
Since Ann received $900, hence:
Total ratio: 5+7+9=21
(9/21) * x = 3300
* 7 ((9/21) * x = 3300) * 7
3x = 23100
x = $7700
The sum of the money that was between the three friends was $7700.
