7 divided by 20 is what answers
Montano1993 [528]
Hello! 

The Correct Answer to this is that <span>7 divided by 20 or 7/20 equals:

"7/20 = 0.35"

</span>Explanation:

Since you are trying to find equivalent values for 7/20, you can make two proportions and set them equal to each other. The following states that "7 out of 20 is equal to some amount out of 100."

<span><span>7/20</span>=<span>x/100</span></span>

Solve by cross multiplying:

<span>20x=700</span>

Divide both sides by 20 to isolate x:

<span>x=35</span><span> Therefore, </span><span><span>7/20</span>=<span>35/100</span></span><span>. This is the same as saying 35%, since by definition "per" means out of, and "cent" means hundred. To make it into a decimal just move the decimal place two digits to the left, such that 35.00 becomes 0.35, and 100.00 becomes 1. Then it is simply </span><span>0.35/1</span><span>, or 0.35</span>

<span>
Hope this Helps! Have A Wonderful Day! :)</span>
