Ireally need i’ll try to give u brainlliest if i can. : (

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.

The decimal expansion would be .27 repeated
