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.
Calculation of the no of yellow fish and red fish:
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
