This is my question:

If something costs £5200 with a 20% discount what is the original price... I keep getting stuck on these questions, any tips for remembering it?

I really need fast help??

So the price you have is 80% of the full price, so to get 100% you need to divide by 80 and multiply by 100. You divide by the percentage you have, and multiply by the percentage you want.

This is the same as multiplying by 100/80 which is 5/4 or 125%.

I hope this makes sense.

5200 is 80% of the original price since you saved 20%. Divide 5200 by 80 and multiply that answer by 100 = 6500 original price

Thank you!!
