Answer:
1st girl- 2000
2nd girl- 3000
3rd girl- 7000
Step-by-step explanation:
1) add the ratio given: 2+3+7=12
2) the answer that you get is the whole and it is equal to the total: 12/12=12000
3) so now you'll simplify to get the share of each girl: 12/12=12000, what about 2/12(for the first girl)
12/12=12000, what about 3/12(for the 2nd girl)
12/12=12000, what about 7/12(for the 3rd girl)
4) after getting the answer for each, you can add their shares to see if they are equivalent to the total share
