To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write as a percent, we need to find a fraction equivalent to that has a 100 in the denominator. We can do this by setting up a proportion.
=
Now, we can use cross products to find the missing value.
25n = 300
÷3 ÷3
N = 12
Therefore, is equal to or 12%.
1. a=c
2.
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
Options 2 and 5 i.e., and are the correct statements such that .
Ratio is the mathematical indication that tells how many times one number contains another.
Reciprocate the given proportion both sides-
So, option 2 is correct.
Now, if then, the proportion will become-
So, option 5 is correct.
Thus, options 2 and 5 are the correct statements.

Answer:
Leslie can make 10 packs, each having 2 apples and 3 cookies.
Step-by-step explanation:
We have been given that Leslie is in charge of packing snacks for her class she has 30 cookies and 20 apples. She wants to put the same number of apples in each pack.
To solve our given problem, we will find greatest common factor of 30 and 20.
Factors of 20: 1, 2, 4, 5, 10, 20.
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30.
We can see that 10 is the greatest common factor of 30 and 20, therefore, Leslie can make 10 packs.
Therefore, there would be 2 apples and 3 cookies in each pack.
well u move all the variables to the left side, so 8x is already in the left but 7x isnt so you move 7x to the left side of the equal sign which makes 7x to -7x.
8x-2-7x=-9
you move the -2 to the right side of the equal sign which becomes +2.
8x-7x=-9+2
you do the math which 8x-7x=1x and -9+2=-7
so.... 1x=-7
and x=-7. Make sure to always combine like terms.
To make sure it is correct replace the x with the -7 and
8(-7)-2=-9+7(-7)
-56-2=-9-49
-58=-58
so x= -7
