Step-by-step explanation:
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>

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