Answer 2

Im doing (a) first

Answer 3

i think the answer is 12% over 250

Answer 4

Well, a percent proportion is this
\(\rm\dfrac{part}{whole}=\dfrac{percent}{100}\)

Answer 5

Do you know what our part, whole, and percent is? If there is none for it, then say unknown

Answer 6

12 is the percent

Answer 7

Just for know, because we will be solving for the unknown value

Answer 8

250 is the whole

Answer 9

Right, so

\(\rm\dfrac{part}{whole}=\dfrac{12}{100}\)

Answer 10

Yes, so
\(\rm\dfrac{part}{250}=\dfrac{12}{100}\)

Answer 11

\[12 / 100=0.12\]

Answer 12

Do you know how to solve this?

Answer 13

Good so far :P

Answer 14

\(\rm\dfrac{part}{250}= 0.12\)

Answer 15

idk the part how do i get the part

Answer 16

You just solve it like an equation. Multiply both sides of the equation by 250

\(\rm\dfrac{part}{250}\times250=0.12\times 250\)

\(\rm part=0.12\times 250\)

Answer 17

30

Answer 18

Correct, so

\(\rm part = 30\)
