Homework Help: Solving Ratios in Mathematics?

1 Answer

Answer :

answer:The first step is to combine the two ratios A:B and B:C into one ratio A:B:C. A:B = 5:2 = 15:6 B:C = 3:2 = 6:4 A:B:C = 15:6:4 Now, this means that if you had 25 grams of salt, then 15g would be in can A, 6g in B, and 4g in C. You have 750 = 25*30 grams of salt, so these numbers must also be multiplied by 30. 450g in A 180g in B 120g in C

Since y is a two digit number ... 989 + 10 = 999. We can't go any higher, so x =999 and y=10. x+y = 999+10 = 1009
