Answer: Percent means 'per 100'. So, 830% means 830 per 100 or simply 830/100.

If you divide 830 by 100, you'll get 8.3 (a decimal number). Read more below on this webpage.

As you can see, to convert from percent to decimal just divide the percent value (830) by 100, and remove the "%" sign.

Convert from percent to decimal. Here is the answer to the question: 830 as a decimal or How to convert 830% into a decimal equivalent. Use our percent to the decimal calculator above to write any percent values as a decimal.

Percent means 'per 100'. So, 830% means 830 per 100 or simply 830/100.

If you divide 830 by 100, you get 8.3 (a decimal number).

So, to convert from percent to decimal, simply divide by 100 and remove the '%' sign.

There is an easy way to convert from percent to decimal: Just move the decimal point 2 places to the left. Note that if the percent value is a integer, the '.' is at the right of the rightmost digit.

I hope this helps...

the frame of a picture is 28 cm by 32 cm outside and is of uniform width.What is the width of the frame if 192 cm2 of the pictur
natita [175]

Answer:

The width of the frame is equal to 8\ cm  

Step-by-step explanation:

Let

x-------> the width of the frame picture

we know that

(28-2x)(32-2x)=192    

896-56x-64x+4x^{2} =192

4x^{2}-120x+704=0  

Simplify

x^{2}-30x+176=0

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^{2}-30x+176=0

so

a=1\\b=-30\\c=176

substitute in the formula

x=\frac{30(+/-)\sqrt{(-30)^{2}-4(1)(176)}} {2(1)}

x=\frac{30(+/-)\sqrt{196}} {2}

x=\frac{30(+/-)14} {2}

x=\frac{30+14} {2}=22\ cm  ----> this solution is not logic

x=\frac{30-14} {2}=8\ cm  

The width of the frame is equal to 8\ cm
