1:3:5
firstly u need to find out how much one will get so u will add all the ratios 1:3:5 and divide by 72k(72000) so you will get 8000
therefore 1 will get 8000
3 will get 8000 multiply by 3 =24000
5 will get 8000 multiply by 5 = 40000

5.637 x 10^3 that’s all iv got
You got it right because you solved it correctly
