Change fraction to decimal: 4/7 and round to the nearest thousandth?

To solve this problem, all we have to remember is that fractions also mean division. Therefore this means that:

4 / 7 = 4 divided by 7

We can use either a calculator to solve for this or do the long division method of division (your choice). Now to solve this simply, I used the calculator and got the answer:

4 / 7 = 0.571428571

However, the problem asked us to round this to the nearest thousandth. We know that the decimal places are:

0. (tenths) (hundredths) (thousandths)

So we are to round this into 3 decimal numbers which gives us:

4 / 7 = 0.571
