Acereal bar is increased in price by 8%. the new price is 81p. what was the original price of the bar?

If the price is now 81 cents and the price was 8% less the price would have been 64 cents.

Alright so I find it much easier to divide fractions by doing keep, switch flip. U might not have been taught this but it’s very helpful. So keep the first number, switch the division sign into multiplication sign and flip the fraction (so the decominator is now the numerator and vice versa)
