Kerrie uses the work shown below to determine 35% of 280.
2 answers:
For this case we must find 35% of 280.
Kerrie gets 10% and then 25%. So:
10% of 280:
280 ------------> 100%
x -----------------> 10%
Where "x" represents the amount given by 10% of 280.
Thus, 10% of 280 is 28.
Now, we find 25% of 280:
280 ------------> 100%
x -----------------> 25%
Where "x" represents the amount given by 25% of 280.
Thus, 25% of 280 is 70.
So we have that 35% of 280 is given by:
So, Kerrie's solution is correct.
Answer:
Option A
Answer:
<h2>Kerrie's solution is correct.</h2>Step-by-step explanation:
Each step of Kerrie's solution is correct, because 10% + 25% is actually 35%. Also, 10% of 280 is 28, because we divide 280 by 10. The third step is also correct because 25% is the same as the fourth part, or divide by four, because 25% is the fourth part of 100%.
At last, the sum 70 + 28 is also correct, because it results in 98.
Basically, Kerrie made a different process, but it gives the same result. Because we only could do it like this:
Then,
As you can see, it results the same number.
