let's say you have 1240 you spent most of it an you have only 496 left. how can you find the percentage. can you show me?
Jim paddles from one shore of a lake three miles wide at 4 mph, and John paddles from the opposite shore at 5 mph. How long will they travel before they meet?
A. 20 minutes
B. 27 minutes
C. 1 hour, 24 minutes
D. 3 hours
can you get me started on this?
I do not know you work with pounds, Euros or dollars. Let's use dollars.
If you have 12 dollars, and you have 9 dollars left.
Then you have spent 12-9=3 dollars.
The percentage spent is 3/12*100=25%
i.e.
amount spent/original amount*100%
The percentage of the amount left is, similarly,
9/12*100=75%, or
amount left/original amount * 100%
Suggestion: if you have a different problem, you are better off posting a new thread.
Paddling problem:
If the Jim and John paddle towards each other, the relative speed is the sum of the two, namely 4+5=9.
The lake is three mile wide, so time taken should be 3/9 hour= 1/3 hour=20 minutes.

DO post multiple questions in the same thread if they are similar in nature, so there will be a continuity of explanations.
To find the percentage of an amount, you can follow these steps:
Step 1: Calculate the difference between the starting amount and the remaining amount.
In this case, the starting amount is 1240 and the remaining amount is 496. So, the difference is 1240 - 496 = 744.
Step 2: Divide the difference by the starting amount.
Divide 744 by 1240 and you'll get 0.6.
Step 3: Multiply the result by 100 to get the percentage.
Multiply 0.6 by 100, which gives you 60%.
So, the percentage would be 60%.
To summarize, to find the percentage when given an initial amount and the remaining amount:
1. Calculate the difference between the initial amount and the remaining amount.
2. Divide the difference by the initial amount.
3. Multiply the result by 100 to obtain the percentage.
