C.

Answer 1

convert the fraction to a decimal, multiply by 100 to find the percent

Answer 2

The given fraction is 1/20

Answer 3

do you know how to convert that to decimal using division?

Answer 4

alternatively you can just get it in terms of 100 like so \(\dfrac{1}{20}=\dfrac{x}{100}\)

Answer 5

1/20=5/100?

Answer 6

exactly, and percent just means out of 100

Answer 7

so. ugh. a?

Answer 8

b, 5/100 = 5% = 0.05

if percent is out of 100, and we have 5 out of 100, that means we have 5 percent

Answer 9

Ohhh. Whoops. Didnt read it correctly. So I think i get it now.

Answer 10

do you want me to write out the steps more in depth?

Answer 11

Uhh. I dont think so i think i got it. My next one is kinda tricky tho. I have to find a percent that is equivalent to 7 1/4 do i just do the same thing?

Answer 12

first get it into improper form

Answer 13

Okay so to do that i 7x4+1?

Answer 14

You don't need to convert Anything to improper form.

Answer 15

Converting to improper form is not a correct approach.

Answer 16

if we're making the denominator 100, it is
or she can just convert it to decimal

there is no single correct approach, your input isn't appreciated if you aren't going to be constructive

Answer 17

Now im confuzzled.

Answer 18

just do what I say until he can justify himself

Answer 19

Okay.

Answer 20

also yeah, sorry I didn't see that post earlier. \(7 \dfrac{1}{4} = \dfrac{7*4+1}{4} =\dfrac{29}{4}\)
then we want \(\dfrac{29}{4}=\dfrac{x}{100}\)

alternatively, we can just convert it to decimal using a calculator. \(7\dfrac{1}{4}=7.25\)

then we divide by 100 to find the percent. \(\dfrac{7.25}{100}=x%\)

Answer 21

\(\dfrac{7.25}{100}=x\%\) *

Answer 22

uhh.

Answer 23

dividing by 100 means we move the decimal two places to the left

Answer 24

the basic rule is converting decimal to percent: move the decimal point two places right
converting percent to decimal: move the decimal two places left
