Welcome! Today we'll learn how to divide fractions using a simple method called "Keep, Change, Flip". This rule makes fraction division as easy as multiplication. Let's see how it works step by step.
The first step in dividing fractions is the easiest one: just keep the first fraction exactly as it is. Don't change anything about it - not the numerator, not the denominator. In our example of three-fourths divided by two-fifths, we simply keep the three-fourths unchanged.
The second step is to change the division sign to a multiplication sign. This is where the magic happens! Instead of dividing by a fraction, we're going to multiply by something special. Change that division symbol to multiplication, and we're ready for the final step.
The third and final step is to flip the second fraction - this means swapping the numerator and denominator. So two-fifths becomes five-halves. This flipped fraction is called the reciprocal. Now instead of dividing by two-fifths, we're multiplying by five-halves, which is much easier to calculate!
Let's put it all together! Starting with three-fourths divided by two-fifths, we apply Keep-Change-Flip: Keep three-fourths, change division to multiplication, and flip two-fifths to get five-halves. Now we multiply: three times five equals fifteen, and four times two equals eight. So our final answer is fifteen-eighths. And that's how easy fraction division can be with Keep-Change-Flip!
