Question

Sean, Ryan, and Justin shared a sum of money in the ratio 3 : 4 : 5. If Sean received $30, what was the sum of money shared?

Answer 1

In order to solve this problem, you need to find out how 3 of something is 30
In this case, you multiply 10.
Sean= 3×10=30
Ryan= 4×10=40
Justin= 5×10= 50
30+40+50= 120
The answer is $120
Hope this helps
