Miss Sue, I think you missed the "0" before 45 (0.045 not 0.45) 0.045 = 45/1000 = 9/200 = 0.045 So, the fraction is, 45/1000 = 9/200 (reduced to lowest terms) 0.045 * 100 = 4.5% So, the percent is, 4.5%

Are 22, 16, and 28 the sides of this triangle? What is "a nine in the middle" mean? What does this "9" represent? Your question cannot be answered as worded. What exactly does your problem say or state to do?
denominators
You need to use parenthesis. If this is your problem v/(v+5)+v/3 = -4/(v+5) Multiply both sides by 3(v+5) 3v + v(v + 5) = -12 3v + v^2 + 5v = 12 v^2 + 8v + 12 = 0 (v + 2)(v + 6) v = -6 or v = -2 Make sure you check the solutions in the original equation. I have NOT checked the...
