If 75% of your money is 420, and you want to figure out how much half of it is, then you might have to figure out how much all of it is first. Since 75% is 3/4 of 100%, you can didvide 75% by three. This will get you 25%. You will then find 25% of 420, which is 105. Next, multiply 105 by four, any you will get 100% of your money. 105 times four is 420. ... Oh. Well, then.... How? 420 is 75% ... but I got 420 as 100% ...this is confusing. Sorry, I don't have the answer. (Whaaa?)
Answer: 280
Explanation: So, if we convert all the parts of numbers into fractions, 75% would become 3/4. Because 420 is 3/4 of your money, then you can divide 420 by 3 (the 3 for 3 out of 4 parts of your money) to get what 1/4 of your money, in this case, 140. Since you need to find what 1/2 of your money is, you turn this into 2/4 (which is the same value) to make it easier to visualize. As 1/4 of your money is 140, then you can multiply that by 2 to get 2/4 (or 1/2), resulting in 280.
Hope this helps you to understand because this is math that you might actually use in the future :)
