Answer:
Mental Math and Logic
Step-by-step explanation:
You might not have access to a calculator, so when times comes like this when you have to validate a statement if wrong or right, mental math comes in help.
You only need the approximate number to do something like mental math. Both numbers divided by each other, is really close to their whole numbers of 1 and 5, respectively. If you divide 1/5, you get 0.2, which is not what the answer is. 0.02 and 0.2 are very different answers, and you would not get 0.02 no matter how many decimals after that 1.0 and 5.0.
Which means the statement is not true based on logic and mental math.
This requires us to find the number of permutations of 6 different bands taken 2 at a time:
I think it's 7 1/2 because you can turn 30 1/4 to 15/2, which simplifies to 7 1/2
You take the numbers that are above 5 and put them up one to the next tenth then you do that the same for thousands. your anwser would be 900,000
