Explanation

a/b = 10/11 and b/c = 6/7  

Multiply them to get a/c:

a/c = (a/b) × (b/c) = (10/11) × (6/7) = 60/77

So a:c = 60:77

Explanation

Given:  

a/b = 9/10  

b/c = 5/6  

Multiply both equations:  

(a/b) × (b/c) = (9/10) × (5/6)  

a/c = 45/60  

a/c = 3/4  

So a:c = 3:4.

Explanation

Given:

a:b = 8:9

b:c = 3:4

Make b equal in both ratios (LCM of 9 and 3 is 9):

a:b = 8:9

b:c = 9:12

Now combine:

a:b:c = 8:9:12

So, a:c = 8:12 = 2:3

Explanation

a:b = 7:8

b:c = 4:5

Make b same:

a:b = 14:16

b:c = 16:20

Therefore, a:c = 14:20 = 7:10.

Explanation

In 12 L mixture with ratio 1:3:  

Total parts = 1 + 3 = 4  

Water = (1/4) × 12 = 3 L  

Milk = (3/4) × 12 = 9 L  

Let x liters of water be added. Milk stays 9 L.  

New ratio: (3 + x) : 9 = 2 : 3  

So (3 + x)/9 = 2/3  

3(3 + x) = 18  

9 + 3x = 18  

3x = 9  

x = 3
