How do we use ratios to figure out how much money to give to people of a lump sum?

Lets start with an example scenario:Two people are to receive a percentage of a £500 business sale. One receives 25% and the other receives 75%.
When using percentages we must remember that it means it is per 100. 25% is the same as 25/100.
The total amount of money is £500, which represents 100% of the money.
To calculate how much each person receives, we multiply the total amount of money by their percentage, remembering that the percentage means per 100.
25/100 x 500 = £125 75/100 x 500 = £375
To check that we have the right answer, we can add the two numbers together and it should equal the amount we started with.
£125 + £375 = £500
This is the amount we started with, meaning we (probably!) have the right answers!
