Make them both integers by mutliplying both by 100 (get rid of the decimal points), then its a straightfoward division.

I know that you know that you only need to make the divider an integer but in this case both become integers.

The OP might think, from what you wrote, that both need to be integers.

For me, the "easiest way" would be to use a calculator

So you probably wanted to say that you're trying to do this calculation manually, in which case make the denominator as simple as possible - multiplying by 100 will turn that awkward looking 0.06 into a '6' and then you have to multiply the numerator by the same number (100) so that you're not changing the value of the fraction before you do the division.

This particular example is surely easier to do mentally than to bother reaching for a calculator.

well we all have our off days - especially those of us who are not getting any younger

I love practising my mental arithmetic, but if I have to divide decimals in a "real" situation then I'll normally be using a spreadsheet or something to avoid stupid errors (my brain will still tell me if the answer is a "reasonable" size, so I'm mentally checking that I haven't mistyped the digits or the position of a decimal point or something daft!)

We aren't 'getting rid of the decimal points' - they are still there. What we are doing is making the denominator an integer.

Decimal points do not move - the digits do - this is an important aspect of learning in primary

I certainly know what you mean there. I suspect that my arithmetic is at its lowest point in forty years.

Who is getting younger? Billionaires taking the blood of their children?
