let's see if we can write 0.072 seven as a fraction now let's just think about what places these are in this is in the tenths place tents this is in the hundreds place hundreds hundreds place this two is in the thousands place thousands and this seven right here this last seven is in the ten thousands place ten thousands so there's a couple of ways we can do this the way I like to think of this this term right over in the ten thousands place we can view this whole thing right over here 727 ten thousands because this is the smallest term or the smallest place right over here so let's just rewrite it this is equal to 727 over 10,000 over 10,000 and we've already written it as a fraction and I think that's about as simplified as we can get this number up here is not divisible by two it's not divisible by five in fact it's not divisible by three which means it would be divisible by six or nine doesn't even look to see you two seem to be divisible by seven it might be a prime number but I think we are done
