Answer 4

kk

Answer 6

230 - x% of 230 = 180
230- x/100 * 230 = 180
230(1-x/100)=180
lets solve for x

Answer 7

ok

Answer 8

i got 500/23

Answer 9

Here is a formula, personally my favorite:
\[\frac{ greater - lesser }{ original } \times 100\]

Answer 10

230*(1-x/100)=180
230*R=180
R=180/230

1-x/100=180/230
=230/230 - 50/230
1-x/100= 1-50/230
we al most have it looking identical can you do the rest?
