- Help! Kid's maths homework!
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?

http://www.bbc.co.uk/news/education-25187997change 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)

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. ๐

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!I was first up and in just a thick builder!

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

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 ๐
