Answer:

25%

Step-by-step explanation:

1. You have a total of 1,200 students and a fraction of them did not wear their school colors, 300 students.

2. You would write the fraction \frac{300}{1200}.

3. After you divide or simpify  \frac{300}{1200} you get \frac{1}{4}.

4. To get a percent you multiply by 100, so \frac{1}{4} times 100 is equal to 25.

Answer:

<em>20%</em>

Step-by-step explanation:

<em>First, add 1,200, and 300. That gives you 1,500. You want to find how much percent of 1,500 equals 300, and that is 20%.</em>

The are of his backyard is 10.4 times 15.83 or 164.632 yd^2
the sod piecs are 1.33 by 1.33 or 1.78 yd^2

A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was t
quester [9]

Number of registrations a website received during July = 2500

Number of registrations a website received during August = 2245

Number by which the registrations decreased :

=\tt 2500 - 2245

=\tt 255

Thus, the registrations decreased by 255.

Let x be the perrcentage of decrease.

Which means :

=\tt 255 =  \frac{x}{100}  \: of \: 2500

= \tt255 =  \frac{x \times 2500}{100}

=\tt 255 =  \frac{2500x}{100}

= \tt255 \times 100  = 2500x

= \tt25500 = 2500x

=\tt  \frac{25000}{2500}  = x

\color{plum} =\tt  \bold{10.2\%}

▪︎Thus, the percentage of decrease in the number of registered members = 10.2%
