Answer 1
Answer: Before I give you the answers, there is a simple rule to observe when rounding a number to two decimal places. If the number in the third decimal place is less than five, then the number in the second decimal place stays the same. If the number in the third decimal place is five or greater than five, the number in the second decimal place is incremented by one. In our case the above numbers are rounded up as follows:

0.273 is rounded up to 0.27
1.595 is rounded up to 1.60
6.473 is rounded up to 6.47
2.571 is rounded up to 2.57
0.425 is rounded up to 0.43
44.5564 is rounded up to 44.56
82.3643 is rounded up to 82.36
325.1741 is rounded up to 325.17

Two-fifths time a plus a over 2 equals a minus 2

Answers

Two-fifths time a plus a over 2 equals a minus 2 will be a=20

Step-by-step explanation:

We have to find a, by first writing the verbal expression into an arithmetic form as,

Two fifths times a = (2/5)a

a over 2 = a/2

a minus 2 = a-2

(2/5)a + (a/2) = a-2

We have to take LCM on LHS as 10.

(2×2 /5×2)a + (a×5 /2×5) = a-2

(4a/10) + (5a/10) = a-2

Moving 10 to the other side, we will get,

4a+ 5a = 10(a-2)

9a = 10a -20

Grouping terms we will get,

10a - 9a = 20

a = 20

The ratios a:b and b:c are equivalent to one anotherSelect all the statements that must be true

1. a=c

2. (b)/(a) = (c)/(b)

3. b-a=c-b

4. a
5. if a=b, then b=c

I think #2 is correct ,but I don't know about the others

Answers

Options 2 and 5 i.e., (b)/(a)=(c)/(b) and b=c are the correct statements such that (a)/(b)=(b)/(c).

Ratio

Ratio is the mathematical indication that tells how many times one number contains another.

How to simplify the ratios?

Reciprocate the given proportion both sides-

(b)/(a)=(c)/(b)

So, option 2 is correct.

Now, if a=b then, the proportion will become-

1=(b)/(c)\nb=c

So, option 5 is correct.

Thus, options 2 and 5 are the correct statements.

Yes, only number 2 is correct.

Your number 4 seems to only consist of a. Hence, I can't make any assumptions based on that.

So yes, only number 2 is correct.
