Ok, a percentage is a number over 100. So 5 percent is 5/100. You can set up a proportion here to get 5/100 = 35/x and cross multiply to find x. After you cross multiply, you get:
5x=3500 and divide both sides by 5 to get x. x=700.
Then you can set up another proportion that reads 0.5/100 = x/700 because you now know that the whole is 700 and you're trying to find part of the whole. Again, you cross multiply and get:
100x=350 and you divide both sides by 100 to get x.
x=3.5 is your answer!
Another way you could do this, which is simpler, is divide 35 by 10 because 5/.5 = 10. So 10 is the factor by which you need to divide 35 by to get your new answer.
I hope you could follow all that. Good luck on your math endeavors!
extra user-friendly thank you to sparkling up: 3/2(3x + 5) = -24 Multiply each and everything by potential of two to cancel off the denominator: 3(3x + 5) = -40 8 amplify the brackets: 9x + 15 = -40 8 Subtract 15 from the two sides: 9x = -sixty 3 Divide the two sides by potential of 9: x = -7 ———————— to reply to your preliminary question: 2/3 x -24/a million = -40 8/3 = -sixteen

5/100 = 35/x
5x = 3500
x = 700
0.005*700 = 3.5 << answer
