How do you write seven hundred thousandths as a decimal?

Answer 1

Technically, the way the question is written, we can't tell whether you mean 0.700 or 0.00007 Assuming this is a tolerance specification in a machine shop or similar, it's probably stated in 'thousandths' of an inch, so the decimal is 0.700 inch

Answer 2

Seven hundred thousandths written as a decimal is 700/1000, or 7/10 in simplest form.
