Step 1: We need to match the b portions of each ratio:

Using our LCM Calculator, we find that the least common multiple of 4 and 6 is 12

Step 2: For our a:b ratio of 5 : 4, we need to multiply each portion of the ratio by 12 ÷ 4 = 3

3 x 5 : 3 x 4 = 15 : 12 ← Our new a : b ratio

Step 3: For our b:c ratio of 6 : 5, we need to multiply each portion of the ratio by 12 ÷ 6 = 2

2 x 6 : 2 x 5 = 12 : 10 ← Our new b : c ratio

The b portions of each ratio match, and we have a : c = 15 : 10 Using our GCF Calculator, we can simplify both parts of our ratio by 5 We can express our ratio as a fraction

15/5

10/5

3

2

Since the b portions of each ratio match, we just take a : c = 3 : 2

What is the Answer?

Since the b portions of each ratio match, we just take a : c = 3 : 2
