Question

If a:b = 5:3 and b:c= 2:3, what is the ratio a:c?

Answer 1

I think its 5:2

Explanation:

a:b= 5:3

b:c=2:3

3 is in both ratios and so is b so b=3

5=a

2=c

Answer 2

• 10 : 9

Explanation:

Given:

• a/b = 5/3
• b/c = 2/3

Find the value of a and c:

• a = 5b/3
• c = 3b/2

Find the ratio a to c:

• a/c =
• 5b/3 : 3b/2 =
• 5b/3 * 2/3b =
• 5*2/3*3 =
• 10/9
