This is a YouTube educational video titled "Converting Fractions To Percentages With Denominators Of 10 Or 100" (created 2024-04-10). The transcript is an instructional lesson between two presenters — one introduces herself as Florence (SPEAKER A) and a second speaker (SPEAKER B) — explaining how to convert fractions with denominators 10 or 100 into percentages, using visual representations and simple examples (including simplifying 36% to a fraction).

Hi, I'm Florence. And today we're going to look at converting fractions to percentages. We're going to focus on fractions where.
The denominator is 10 or 100. So really, the examples in this video.
Are designed for introducing pupils to the concept.
The first thing to remember is that.
Percent is a out of 100.
That's what it means.
And in fact, that's where the percent.
Symbol comes from, and that's why it looks like that. So for that reason, the fractions that.
Are the easiest to convert into percentages.
Are those that are already out of 100, are those that have a denominator that's 100. So 100th, you can see it represented visually. There is 1%, 20 five hundredths, 25 out of a possible hundred. Again, we have our visual representation. Is 25%. When the denominator in a fraction is.
10, we can convert that into hundredths.
And our visual representation again helps us.
To see that 1 out of 10 equal parts is the same as 10 hundredths. So 1 10th is the same as 10 hundredths.
And now that our denominator is 100, we can straightaway identify the percentage by looking at our numerator. Ten hundredths is 10%.
4/10. Similarly, we can see we have 10, 20, 30, 40 out of a possible hundred. So we can convert it to 40%. And you might start off by using.
These visuals, but obviously you want pupils to be able to make those links eventually without having those there to help them. So in this last example, we have a percentage and we need to convert.
It into a fraction. That's really simple because If Caleb scored 36%, then as a fraction, we can express that as 36 out of 100.
Because percent is always out of 100. The question, however, asks us to give the answer in its simplest form. So we can simplify it by dividing both our numerator and denominator by four gives us.
Nine, twenty fifths.
Now, as I said, these are kind.
Of more of the basics in terms of converting between fractions and percentages. And if you want to see some.
More complex examples, then watch our next video, which looks at more complex ways.
