How do I write this?

1.37

Step-by-step explanation:

In numbers with a decimal there are many ways to look at it. The easiest way to remember in my personal opinion is this:

Any number before "." is on the left side, or before the decimal.

Any number after "." is on the right side, or after the decimal.

When the number is written out like "one and thirty-seven thousandths," "and" is where the decimal will be.

So, in this example we have: one (1) and (.) thirty-seven (37) thousandths.
