The equation is to find the difference between 14.99 and 15.55.
My working out way is the number line. So you start at the lower number which is 14.99 + what = 15.55.
So I did 14.99 + 0.01 = 15 because it is more easy to add another decimal to a whole number. The next thing I did was 15 + 0.55 = 15.55. Then I am going to add 0.01 + 0.55 = 0.56. But now they have the same time so Jayde has to swim 0.01 to beat Paikea.
