I’m not sure how to solve the first one but the second one (c) is 24. You have to see the pattern between 15 and 45 and then do that to the denominators. The pattern is multiplying by 3 (15x3 =45) so multiply 8 by 3 and you get 24. Hope this helps and if not, please message me for further help.

For the first one, cross multiply 15 and c which is 15c and cross multiply 8 and 45 which is 360, so u get 15c = 360 and divide 15 c by 15 and 360 by 15 also then the answer would be c = 24

For the second one it’s basically the same thing, cross multiply x and 12 which is 12x and 8 and 3 which is 24, then you get 12x = 24. Divide both sides by 12 and the answer would be x = 2
