Answer:
Don caught 3.6 kg and Dan caught 0.6 kg.
Step-by-step explanation:
Set up a system of equations:
Don's fish is the variable a and Dan's fish is the variable b.
a + b = 4.2 (1)
a=6b (2)
We can substitute a in the first equation using the second equation, so:
6b + b = 4.2
7b = 4.2
b = 0.6 kg
Dan caught 0.6 kg. Then, we can use equation 2 to find how much Don caught.
a = 6 x 0.6
a = 3.6
Don caught 3.6 kg.
