Question 315259: I need you help please. I need to show answers in decimal, fraction, percent, exponent and scientific notation. The problem is 2^3/2^7. What I came up with is in decimal it would be 0.062. In scientific notation would be 1.6*10^1. In fraction it would be 1/16. I need help in converting to percentage. Are the other answers correct? Please advise. Thank you.

You can put this solution on YOUR website!
2%5E3%2F2%5E7=2%5E%283-7%29=2%5E%28-4%29=1%2F%282%5E4%29=1%2F16 <--- CORRECT!
In decimal form,
1%2F16=0.0625 <--- CORRECT!
Now switching from decimal to scientific, you lost something.
To go from decimal to scientific, move the decimal point over two places, and add an exponent of 2 (from the 2 place move).
0.0625=6.25x10%5E%282%29
The last one you need is percent.
Percent means out of 100.
0.0625=X%2F100
Solve for X and then your answer is X%.
