Find fractional notation and simplify 32and 1/8%=?

Question

And Help me out wit this to solving for N question 2/18 = N/27???
$72 is what percent of $96. What Is 4% of 1000
And Finally find percent notation 9/16?????

Answer 1

2/18=N/27
N=2*27/18
=3

2.72/96 *100=75%

3.4/100*1000=40

4.9/16*100=56.25%

Answer 2

For 2/18 = N/27, use cross multiplication, so multiply 2 x 27 = N x 18, so you'll have, 54 = 18N. Now, solve for N, so divide both sides by 18, and N equals 3.

To find what percentage, $72 is of $96, simply divide 96 into 72, and that will produce the answer, so 72/96 = 75%.

So, when they give you a percentage, and a numerical, value, multiplication is used (the opposite of division) in order to find the number in question. Multiply .04 ( decimal version of 4% ) x 1000 to find the answer. Answer = 400.

9/16 = 0.5265. If it was 8/16, that would be 1/2 or 50% or 0.50. But since, 9 is more than 8, it can be expected that the decimal value will be more than 0.50.

Answer 3

all of your questions can be solved as proprotions. To solve a proportion, write them side by side and cross multiply. Upstairs times downstairs divided by the leftover gives you the answer. That is ...

2 N
-- = -----
18 27 (2 X 27) / 18 = 54 / 18 = 3 = N
This one could also be solved by inspection if you reduce 2/18 = 1/9, then multiply top and bottom by 3. but if you're the sort who solves stuff by inspection you'd probably not ask. Anyhoo...
72 N
------ = -------
96 100 N = (72 X 100) / 96 = 75
You could also solve this one easily if you reduce 72 / 96, divide top and bottom by 8 and you get 9/12, then by 3 and you get 3/4, which is 75%.
4% of 1000
4 N
--- = -------
100 1000 N = (4X1000)/100 = 40
You could also solve this one by recognising that in proportion problems, "of" means "times" or "multiply." So 4% of 1000 means 4% x 1000 = .04 X 1000 = 40.
Percent notation 9/16
9 N
---= -----
16 1000 N = (9 X 1000) / 16 56.25
you can do all sorts of cool things with proportions
