Answer 1

A:B:C:D =7:9 BECAUSE A:B = 2:3 and C:D= 6:7

Answer 2

Answer:

A:B      B:C     C:D

2:3       4:5     6:7

Equate B first by multiplying A:B from 4 and B:C from 3, you'll get:

A:B     B:C       C:D

8:12    12:15     6:7

Now equate C by multiplying, A:B and B:C by 2 and C:D by 5, you'll get:

A:B           B:C         C:D

16:24      24:30      30:35

Therefore, new ratios of A:B:C:D will be 16:24:30:35
