I Think it is atomic mass
8% as a decimal and fraction would be 0.8 and 
It should just be 3 15/16 because you can’t really simplify 15/16 because it’ll just give you decimals. For example; 15/3 is 5 but 16/3 is 5.333.... and 15/5 is 3 and 16/5 is 3.2, and 15/2 is 7.5 and that won’t work because it turns into a decimal.
Answer: 2 to 1 and 2;1
Step-by-step explanation:
in general there are 3 ways to write these ratios. A fraction, the one using to, and the ones with semicolans. This is how you will always want to write your ratios on the problems you are solving with your ratios when it asks that.
Answer:
$41
Step-by-step explanation:
- One room rents for $68,
- Two rooms for $65 each,
- In general, the group rate per room is found by taking $3 off the base of $68 for each extra room.
So,
where 
is the rate per nth room rented.
This is an arithmetic sequence, so
In your case,
Hence
This means if a group rents 10 rooms, the charge per room is $41.
