9.3 and were closest to another.
<u><em>Explanation</em></u>
First we will convert each given fractions into decimal form. So....
Then the scores are: 9.30, 9.50, 9.80, 9.95 and 9.25
So, 9.30 and 9.25 are closest to another as their difference is (9.30-9.25)=0.05
That means , 9.3 and were closest to another.
<span>How can you make 10 when
adding 8 + 5?
Well, let’s try:
Adding 8 and 5 is equals to 13
=> 8+5=13 (How can you get 10)
Well 13 has 2 digits where 3 is placed in ones and 1 is place in tens.
Therefore adding 8 and 5 will result to 10.

Assume the secret number is x.
"Al doubled the number and added 15 to the result. He got 51."
means 2x+15=51
solving for x:
2x+15=51
2x=51-15
2x=36
x=18
"Beverly did the same operations with their number, but in the reversed order." means she first added 15 to the number, then she doubled the result,
that is she performed the operation:
First: x+15
then: 2(x+15)
since we found x=18, then we have 2(x+15)=2(18+15)=2*33=66
Answer: 66
