Answer:

50%

Step-by-step explanation:

the percent of decrease from 10 to 5 is 50%

When 10 is decreased to 5:

10-5= 5

5 is half of 10.

1/2 as a percent is 50%

Answer:

Step-by-step explanation:

To find percentage difference (whether increase or decrease), you need to first find the difference by subtracting the original value from the new value;

Then, you divide this by the original value and then multiply by 100, so:

% difference = 100(new - original)/original;

So, to apply this:

% difference = 100(5-10)/10

= -50%

The negative sign indicates a decrease, whilst a positive value would mean an increase;

You must be careful how you phrase this, if using the negative sign, so:

You can say a -50% difference or a 50% decrease.

P.S. If you mention that it is a percentage decrease, do not include the negative sign, if simply stating that it is a percentage change or difference then you can include the negative sign, which will make it clear that it is a decrease from the original value.

First, when multiplying percents, you need to convert them to decimals. You convert percents to decimals by multiplying by 100 or moving the decimal two places to the left. Once you convert them to full decimals, you multiply the decimal by the number that you are getting the percentage from

61% of 180⇒.61×180=<u>109.8 </u>

5.1% of 81?⇒.051×81=<u>4.131

</u>16 \frac{1}{2} of 36?⇒16.5×36⇒.165×36=<u>5.94

</u>81% of 241⇒.81×241=<u>195.21</u>

76% of 600⇒.76×600=<u>456</u>

88% of 680⇒.88×680=<u>598.4</u>

37% of 481⇒.37×481=<u>177.97</u>

19.1% of 380⇒.191×380=<u>72.58</u>

41% of 321⇒.41×321=<u>131.61</u>
