A charity sent out 700 fundraising letters and received 210 contributions in response. What was the percent of response?
Pavlova-9 [17]
To find the answer, you have to make a proportion. 210 out of 700, or 210/700 is equal to x/100. So, 210/700=x/100. Then to solve the proportion, you must cross multiply. 210 times 100 is 21,000. Then, you must divide 21,000 by 700, which is 30. The 30 represents 30/100, which is 30%
The answer is 30%.

Answer:

Step-by-step explanation:

I am not clear your question.

5^(-2) / ( 5^(-3) * 5^(4))

When base is equal at multifaction index should be add.

ie. (-3)  + 4 =1

5^(-2) / ( 5^((-3) +4))

5^(-2) / ( 5^(1))

When base is equal at division index should be substract.

5^(-2) / ( 5^(1))

5^((-2 )+ (-1) )

5^(-3)

We know a^(-2)= 1/ a^2

1/ 5^(3)
