When dealing with fractions of a whole, realize that there are a numerator and a denominator in every fraction. So, the numerator is on top, and the denominator is on the bottom.

So, we have a fraction bar right here, and so first, we need to determine what goes in the denominator. So, that’s the total of a number of spaces we have on the fraction strip.

[divider]The following transcript is provided for your convenience.[divider]So, we have the fraction strip right here, so we need to count the total amount of spaces. So, count with me. One, two, three, four, five, six, seven, eight. So, you need to put an eight in the denominator here.

Now, when it comes to the numerator, we need to count the shaded spaces. And so, notice these spaces right here, they’re all shaded. So, now, we need to count those. One, two, three, four, five.

So, there are five shaded spaces. And so, the five’s going to go into the numerator, because we have the whole amount right here, and then we have part of the whole.

So, right here, we have a pizza. And so, let’s count the spaces of this pizza. One, two, three, four, five, six, seven, eight.

So, again, if we’re doing a numerator and a denominator, we put eight in the denominator.

So, now, we need to count the shaded regions for the numerator. So, there’s one, two, three, four, five shaded regions.

So, here for this pizza, there were eight total pizzas, so eight is the whole, and then five is how many are still there. So, there are five pieces of pizza still there, so five goes in the numerator.

So, although you may mostly be dealing with the fraction strip, try to take that idea right there and think about just the pizza, and think about, *“Okay, maybe there’s eight or five total pieces of pizza, and how many have not been eaten yet?”* And so, that’s what you’re doing when you look at a fraction strip.

So, remember that the whole goes in the denominator, and then the shaded regions go in the numerator.
