Answer:
The greatest number of tanks is 6 tanks
Step-by-step explanation:
To find the greatest number of tanks that set up to contain 12 angel fish , 24 sword tails and 30 guppies.
We use GCF (Greatest Common Factor) for 12, 24 and 30.
The factors of 12, 24 ,and 30 is
\(12=2\times 2\times 3\)
\(24=2\times 2\times 2\times 3\)
\(30=2\times 3\times 5\)
Therefore, the GCF of 12, 24 and 30 is \(2\cdot 3=6\)
or
since \(6\times(2+4+5\) ) = 12+24+30 fish
therefore, 6 tanks set up with 2 angel fish , 4 sword tails and 5 guppies.
