Help
I have googled fractions and I still dont have a scooby do on how to do Fractions.
One of the questions is 4/5+1/3x3/5 where do I start also (3/5+1/3)x5/7 once again where do I start. I never mastered these at school.
Look forward to hearing from someone

Hi Clare,
If we look at similar examples then this might help you with the assessment questions.
Let's consider 1/3 + 3/4 x 1/5
First we use BIDMAS to tell us where to start. We know that Multiplication is carried out before addition so we would carry out 3/4 x 1/5 first. With Multiplication the process is quite straightforward ( we don't need to worry about a common denominator or anything). We just multiply the two numerators together to give a new numerator and the two denominators together to give a new denominator.
So 3/4 x 1/5 = 3/20
Now we need to do the rest of it which is now
1/3 + 3/20
When we are adding (or subtracting) then we need the denominators to be the same. So we look for the number that 3 and 20 will both go into (60)
We change each fraction to its equivalent fraction with a denominator of 60
1/3 = 20/60 (top and bottom numbers x 20) and 3/20 = 9/60 (top and bottom numbers x 3)
Now we have 20/60 + 9/60 = 29/60 (when we add or subtract fractions we work with the numerators only)
29/60 Is our answer
If we consider an example in the second format (1/3 + 3/4) x 1/5
This time BIDMAS tells us that we need to do the Brackets first
1/3 + 3/4 so we look for a number that 3 and 4 go into (12
1/3 = 4/12 and 3/4 = 9/12 (you can find more on equivalent fractions on bbc skillswise)
So 4/12 + 9/12 = 13/12 ( Don't worry about it being top heavy)
Now for the second part 13/12 x 1/5 = 13/60 (remember times the numerators together for the new numerator and the denominators together for the denominator)
So this time 13/60 is the answer.
Hopefully this helps you. Don't forget, your tutor will be able to help you too.

Re: Introduction to Application of Numbers
Hello there ,
I would like to thank you for your help on these two questions. It helped me and I have finally finished that assignment.
It was a tough one for me as math isnt my strength. I am going to submit my work over this weekend and I hope its what they were looking for.
Have a great weekend. No to crack on with the Maths project shoe sizes
Regards,
Clare
