Swimming Lessons DIMIC

This is my working out


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.
