And 3:4 is in simplest form .

Hope it helps.

The required ratio is b:c = 9:8

Step-by-step explanation:

We are given:

The ratio a:b = 2:3

and the ratio a:c = 3:4

We need to find the ratio b:c

We are given a:b=2:3

We can write it as:

Finding value of a:

Now, we have a:c = 3:4

We can write it as:

Putting value of a and finding b:c

So, we get b/c = 9/8

We can write them in ratio as: b:c = 9:8
