It is known that a / 14 = B / 15 = C / 17 = D / 19 (A*C):(B+A)=( ):( )

It is known that a / 14 = B / 15 = C / 17 = D / 19 (A*C):(B+A)=( ):( )

Let a / 14 = B / 15 = C / 17 = D / 19 = t, then a = 14T, B = 15t, C = 17T, d = 19T
Substitute a, C and B into the left side of the equation = 14 * 17T / 29
So = 14C: 29 or 17a: 29

If 14 of a = 15 of B = 17 of C = 19 of D, what are the ratios of a to B, B to C, C to D, D to D?

Let 14 of a = 15 of B = 17 of C = 19 of D = x, then a = 14x, B = 15x, C = 17x, d = 19x,
So the ratio of a to B is 14x: 15x = 14: 15
The ratio of B to C = 15x: 19x = 15: 19
The ratio of C to d = 17x: 19x = 17: 19

According to a / 14 = B / 15 = C / 17 = D / 19, fill in a: B = (): () B: C = (): () d: B = (): () a: C = (): ()

A:B=14:15,B:C=15:17,D:B=19:15,A:C=14:17
