Fractions In Year 8
Hi
Could somebody please tell me what level & year a child following the UK curricculum would be solving the following:
6/5 + 3/5 x 1/4 7/3 - 2/15 x 3/8
We are following the Greek system of mathematics and are curious as to how this compares to the UK levels. My son is currently in equivalent of year 8.
Many thanks
Jo

Hi Jo,Students could potentially see a sum like this in year 5 if they preparing to sit an 11+ exam but overall in schools you would see these kind of sums in year 6. I would recommend http://www.theschoolrun.com/year-6/year-6-maths for an overview of the kind of topics a student would be expected to study as part of the school curriculum. However there will certainly be overlap in year 7 when a student enters secondary school. Some schools will differentiate work according to current student ability so it could also depend on the school. I am not familiar with the Greek system but a colleague of mine has said that the Greek system in general is quite advanced to what is covered in the UK so you may find that this is the case. Hope this helps :)

6/5 + 3/20 x 7/3 - 1/20= (72 + 21 - 3 )/ 60=90/60 = 3/2

You are missing a sign between the 1/4 and 7/3. But I will assume 4 possibilities below.But remember that order of operations is important. Denominator MUST be the same when you add or subtract fractions!!!(Please Excuse My Dear Aunt Sally)-PEMDAS acronynm:Parenthesis, Exponents, Multiply, Divide, Add, Subtract 1. 6/5 + 3/5 x 1/4 + 7/3 - 2/15 x 3/8 6/5 + 3/20 + 7/3 - 6/120 24/20 + 3/20 + 7/3 - 1/20 27/20 + 140/60 - 3/60 81/60 + 140/60 - 3/60 = 218/60, Reduce = 109/302. 6/5 + 3/5 x 1/4 - 7/3 - 2/15 x 3/8 6/5 + 3/20 - 7/3 - 6/120 24/20 + 3/20 - 7/3 - 1/20 27/20 - 140/60 - 3/60 81/60 - 140/60 - 3/60 = -62/60, Reduce = -31/303. 6/5 + 3/5 x 1/4 x 7/3 - 2/15 x 3/8 6/5 + 21/60 - 6/120 72/60 + 21/60 - 3/60 = 90/60, Reduce = 3/24. 6/5 + 3/5 x (1/4) / (7/3) - 2/15 x 3/8 6/5 + (3/20) / (7/3) - 6/120 6/5 + 3/20 x 3/7 - 1/20 6/5 + 9/140 - 1/20 168/140+ 9/140 - 7/140 = 170/140, Reduce = 17/14
