Answer:
No
Step-by-step explanation:
Find a common denominator, and that is 14. So we convert 1/2 into 7/14 and 2/7 to 4/14, and we see it is not proportional.
Adult : Child
4 : 3
Find out how to get to 152, to get from 4 to 152 you times 38 (4x38=152). You find this out by doing 152 ÷ 4= 38
So you would do the same to the children’s side so:
3x38=114
Add them together:
152+114= 266
All together 266 sold all together
I hope this helped, i tried my best to explain.
