Hi Mr.Berchtold I have a question about letter O the second one so sorry for bothering you
Write in words first...
% / 100 = part (is) / whole (of)
40 / 100 = 18 / x
2 / 5 = 18 / x
multiply both the numerator and denominator by 9 to write an equivalent fraction
x = 45
I don’t get #9 -sorry to bother
9) Original cost: $360, discount percent 33 1/3%
You can multiply 360 * 33 1/3 to find the discount. Or, since there are three groups of 33 1/3% in 100%, you can take $360 and divide it by 3. This gives you the discount of $120. Once you know the discount is $120, subtract 360 - 120 = $240 (sale price)
This answer helped me. Thank you
