Answer:
take 4860 as the sum of the whole ratio. so,
5 + 4 + 3 = 4860. that is:
12 parts = 4860
what about 5, 4, and 3 parts.
12 parts = 4860
5 parts = ?
cross multiply ; 5 × 4860 ÷12 = 2025
do the same to the other numbers to get the answers as,
5 parts = 2025
4 parts = 1620
3 parts = 1215
you can confirm the answers by adding all of them to see if you get 4860.
