Hi Vivian;

I like your name.

I am assuming that we are looking for figures longer than 2.3, and NOT equal to 2.3...

1.7, 2.3, 4.0, 4.4, 5.2

The last three are included in such category.

There are a total of 5 eruptions.

3/5

Percentage means that the denominator is 100.

Let's multiply the numerator and denominator by 20/20...

(3/5)(20/20)=60/100

**60%**

If we are including the figure of 2.3...

1.7, 2.3, 4.0, 4.4, 5.2

4/5

**80%**
