Answer: 1:3
Step-by-step explanation:
<u>Divide both sides by 25:</u>
25/25:75/25
1:3
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.
