what fraction of this circle is shaded red so let's see this circle is divided into one two three four five six seven eight equal parts and of those eight equal parts seven are shaded red so we can say that seven out of eight are shaded red and this isn't how we've traditionally seen fractions when we've written them when we've written them we've written it like this we have written seven over eight are shaded red and actually let me do it in that color although I don't have an exact we get closer to an actual red color so we could literally say seven out of out of them we need like a gray color was listened on shaded seven out of a total eight our shaded red are shaded red that's how we're used to seeing it but sometimes well or usually when we type it in there's no way to write the seven over the eight so instead instead we write seven over eight over eight are shaded red or seven out of eight so let's do that go back to what we were doing so seven out of eight are shaded red let's check our answer let's do two more of these what fraction of the bar is shaded red so the bar has one two three four five six seven eight nine equal sections and eight of them are shaded red so we can say that eight out of nine are shaded red or eight nine or eight over 9 let's do one more what fraction of this circle is shaded red so we have one two three four five six seven eight nine equal sections did I count that right let me come again one two three four five six seven eight nine equal sections and of those one two three four five six seven are shaded red so seven out of nine or seven ninths are shaded red
