This week a couple of people have asked about doing mixed and improper fractions. Because fractions seem to be something that so many people struggle with, I thought I'd create this post with the hope that it will help someone.
These are the fractions where you have a whole number, then a fraction sat next to it. So, for example 1 ½ would work as an example.
To swap this into an improper fraction (where the number at the top of the fraction is bigger, the three steps are simply:
1. Multiply the number at the bottom of the fraction (the denominator) by the whole number.
2. Add the number at the top of the fraction (the numerator) to your answer to step 1.
3. Write the answer to step 2 above the 2 (the original number at the bottom of the fraction.
So, if you were changing 1 ½ into an improper fraction:
2x1 =2
2+1 =3
Answer: 3/2
1. Ask how many times the numerator (bottom number) would go into the top number (denominator) (how many 3’s in 2)
2. This becomes the whole number (Big number or for the official term integer) that sits to the left of the fraction.
3. Write your remainder over the top of the 2 (the original bottom number in the fraction)
Giving you the answer 1 ½
That’s it. The number at the bottom of the fraction never changes (unless they ask you to simplify it but that’s something different but if you want me to explain, please do say).
Each week we send out emails to parents with hints and support on maths, English, and revision (up to the end of GCSE). If you think it would be of help to you or your child and you'd like to receive the emails let me know, and I will happily make sure you receive them as well: info@clarajamestutoring.co.uk
Morning,
I hope the week is going well.
So many people seem to be doing D of E and work experience
at the moment, good luck if that’s you and if you’re at Marlow Camp next
fingers crossed for good weather!
I’ve just finished a lesson on division. It seems to be
something that messes with the brains of so many people.
I found it got easier when I stopped thinking about it as
division and instead thought about it as multiplication. So, if for example I
had the question 396 divided by 3, I would look at it as 3x what = 3. My answer
would be 1. How many times would I need to multiply 3 to get to 9, (my answer
would be 3). Then 3x something = 6. My answer would be 2. Giving me the overall
answer of 132.
I know that’s a really simple example but hopefully it explains
my point.
Thankfully in schools they don’t often seem to need to do
long division, but I’ve worked with a couple of adults (generally nurses for
some reason) who have needed it.
I think I’ll explain this one in a video, as it will be too
complicated to explain it with words as bits get put all over the place. I hope
this makes sense though:
Enjoy the rest of the week and speak soon,
Dawn
