Convert a fraction to percent – Math tutorial

In this math video I (Susanne) explain how to convert fractions to percents. We write the fraction with a denominator of 100 and get the percentage from the numerator. Mathematics explained.

1:52 Example 3
2:21 Example 4
4:02 Example 5

Where was this gem of an instructor when I was a kid? ❤

I got a simpler way. 3 / 8. Divide the denominator into the numerator. You get .375. Multiply that by 100 and you get 37.5, or 37.5%

thanks for showing us how to do these in our heads!

Thank you, Susanne! Finally some concepts within my competence. I love your channel. ❤❤❤❤

After last week's calculus torture, this was very refreshing! I think I knew how to do all this in my head, intuitively, but it's been so long since I learned it in school I'd forgotten what exactly I was doing in my head. Awesome reminder that "percent" is "by 100, " which makes turning things into a percent much simpler!

Great class. If I had had teachers like you, my grades would have improved a lot more, and I'm not complaining. It's very practical and simple. I'll try to follow your channel.

I love your videos.

For percentages, instead of doing cross multiplying or anything, for weird denominator, I take 100 and divide it by the denominator to see what to multiply the numerator by to get the percentage.

[Critmancer]

Very clean method. I don't remember how I learned about these but it always felt easier for me to just multiply the upper part of the fraction by 100. For example if the fraction is A/B and I am looking for x %. x =100a /b. Just works better with my brain

[etaittemps]

Susanne...you're the greatest. Very cool to learn maths (easily) with your videos. Thank you !

[Blue_Dolphin_ov_Vortex]

Yet another brilliant lesson, thank You for sparking the love of math in me again!

I teach GED and ASVAB prep. Giiirrl! You are making my job SOOO much easier! Thank you.

[maheshnawale]

Nice examples, very nice explanation.

I would have become a math expert if the Math Queen and the internet existed when I was a kid.

What a delightful refresher! I'm getting brushed up to help my granddaughter, she's four so I have a minute!

[UptownStore-ye]

Nice examples, full details and I was able to understand it well, thanks.

3:32 okay, that was a solid, clear pitch out of nowhere

12/16=0.75=75% It’s in my head. Input
12/16 = 0.75
Result
True
Left hand side
12/16 = 3/4
Right hand side
0.75 = 3/4
Logarithmic form
log(16, 12) - log(16, 16) = log(16, 0.75)

[HolySoliDeoGloria]

The first example allows for an intuitive solution, but it follows the normal rule: Multiply by 100. We multiply by 100 because we are multiplying by 100% (100% = 100 x 1/100 = 1; we are multiplying by 1, so we are not changing the number at all, just its presentation). 3/100 x 100% = 3%. It shouldn't be presented as an exception or special case, but I do understand that it is "special" in that it is so similar to the final form that you are seeking. Love your explanations and all videos!

[patrickwilkerson]

Nice video. I think just making a ratio such to equal 100 such as:
63/90 = x/100
x/100 = 63/90
x = (63/90) * 100
x = 63/9*10
x = 70%

yes, every thing is good with you Susanne
