To convert a fraction to a decimal, it can be done 2 ways (but one way may not work for each fraction). Having 17/20 means that you can either:
1) Divide 17 by 20 to get a decimal form and then multiply by 100 to get a percentage.
17/20 = .85
.85 x 100 = 85%
or
2) Figure out how to get 20 to equal 100. By this way, you can see that 20 times 5 equals 100. Then just multiply 17 by 5.
20 x 5 = 100
17 x 5 = 85
Therefore the answer is 85%
The answer is B, 85.0%.

Here is an example, hopefully this helps....
Do the following steps to convert a fraction to a percent:
For example: Convert 4/5 to a percent.
Divide the numerator of the fraction by the denominator (e.g. 4 ÷ 5=0.80)
Multiply by 100 (Move the decimal point two places to the right) (e.g. 0.80*100 = 80)
Round the answer to the desired precision.
Follow the answer with the % sign (e.g. 80%)

But, here's how you do your's:
17/20 = 17x5/20x5 = 85%
Multiply the denomintor by whatever number it needs to equal 100. In your case, it's 5. So, you multiply the numerator and denominator both by 5. You get 85/100, which is 85%.

85.0%
put 20 into 17 add a couple of zeros at the end of 17 and will get .85 and multiply by 100 and you get 85%

17/20 as a percent
= 17/20 times 100
= so in working, 100 is divided my 20 (answer is 5) then multiplied by 17.
thus, u get 85% =D
so its B

Well to find the percentage you have to divide 100 by the second number, which in this case is 20. So 20x5=100. Similarly, 17x5=85. So the answer would be B, 85%.
Hope this helps.

whenever there's a fraction, it implies division. so actually divide the 17 by 20. giving you 0.85, now multiply that by 100 to get B. 85.0%

To convert a fraction to a decimal, you divide the numerator by the denominator, so divide 17 by 20. Which is 0.85. So B.

You just take 17 divided by 20. The answer you get is .85, but to change it to a percent, you move the decimal over two places, so your answer is B.
