Answer:

yellow : 8

Red : 4

Step-by-step explanation:

Yellow : Y and Red : R

R : Y = 12

They need to add up to 12 because its the total.

We know that yellow is twice the amount so

4×2= 8

so if yellow was to be times by 2 itd be 8 which will still add up to 12.

The number of yellow fish should be 8 and the number of redfish be 4.

Since Jacob has 12 fish, all of them are either yellow or red. There are twice as much yellow fish as red fish.

Here we assume the redfish be x

So, the yellow be 2x

So

2x + x = 12

3x = 12

x = 4

So, redfish should be 4

And, the yellow fish should be 8
