elcome to math with mister j. In this video, I'm going to show you how to convert a fraction to a decimal. And if you take a look at the top of your screen, it says divide the numerator by the denominator and round if needed. So that's exactly what we are going to do.Now I'm going to do a few of these by hand, a long division problem to show you exactly what's going on. And then the others, I will give you the answer, that a calculator will give you and show you how to interpret everything. So let's jump right into number one where we have two fifths or two over five.So here again divide the numerator by the denominator so two divided by five and this fractiontwo equivalent to two fifths. So we can't do two divided by five, right? We can't take a whole group of five out of that two, so we need to extend our division problem by putting a decimal and a zero. So now, we can think of that as twenty, bring our decimal straight up.How many whole groups of five can we pull out of twenty? Well, four. Four times five is twenty, subtract and we get a zero and that tells us we are done. So two fifths is equal to four tenths.Number two, nine twenty fifths. I'll do this one by hand as well. Sonine divided by twenty five. So we need to, extend our division problem with a decimal and a zero because we can't do nine divided by twenty five and get a whole number. We can't pull a group of twenty five out of nine. So now we think of this as ninety.
