You would do 300/5 since there are 300 catfish
Then multiply the resulting number (60) by 2
The answer is 120

P. S. The inequality sign changed or flipped when there's a negative figure involved.
Hope this helps. - M
If you subtract 1.1 from 5.8 you will end up with 4.7
then you subtract 10^7 from 10^8 which will give you 10^1
then you add the seven back which will give you your answer of
4.7 10^8
