Fractions, and my brain is too old to remember this stuff.
1. What fraction is exactly halfway between 3/5 and 5/7 ?
2. 12500 visitors is an increase of a quarter over last year. How many visitors last year?

23/35
10k
Q2 Divide by 5 and multiply by 4
1 3/5 = 21/35 and 5/7 = 25/35 so exact halfway would be 23/35
2 10000
Wrightyson - 6/10 you need to show your workings
Thanks! A-ha! common denominators?

change both fractions to 35ths (21/35 and 25/35)
If last year was 100%, or 4 quarters; this year was 125% or 5 quarters
to find out what 4 quarters was, take this year, divide by 5 to get one quarter, then x4 (or x4/5)
(or divide by 125 and x 100)

Oh bugger off, he's only 11 and did all the other stuff, including a story about rocket leaves

I'd go round and show him the working out you did on that lump of 4 by 2 in the back of your van.
If this hasn't already been done to death:
1) You're effectively finding the average, add the two togeather and divide by 2.
2) If he's done any algebra: 1.25x = 12500 so x = 12500รท1.25 =10000
Hope that helps!

Far from it; in all seriousness you probably use maths far more than most people!

You're clearly not *that* thick
Those were the sort of real world maths questions that my wife who has an MSc in Teaching Maths struggles to get right (really).
I really meant that the OPP needed to know the technique for working out common denominators etc as well as the actual answer to the question.
We'll go for 10/10 for the answers and 6/10 for the other bit then
Likes fractions, kids and chocolate cupcakes.
