The price of a coat was reduced from $40 to $30. By what percentage was the price of the coat reduced?
Liula [17]

Answer:

The percentage that the coat was reduced is 25%.

Step-by-step explanation:

A percentage is always out of a factor of 100.

40 x 2.5 = 100

30 x 2.5 = 75

75/100 = 3/4

1/4 is missing, which is the percentage.

1/4 = 0.25, or 25%

Hope This Helps!

<span>7/12 is 58.33% </span>
<span>How do we change fractions to percents? </span>
<span>The steps are too simple. </span>

<span>First, divide the numerator (the number at the top of the fraction) by the denominator (the number below the fraction). </span>
<span>In the case above, 7 is the numerator and 12 is the denominator. </span>

<span>So, 7 ÷ 12 = 0.58333 </span>

<span>Then, multiply the result by 100. 0.5833 x 100= 58.33 </span>

<span>Finally, add the percent (%) sign to the result. </span>

<span>Therefore, 7/12 is 58.33%.  <span> </span></span>
