Any one know the answer to this maths sum?

[kid]

4 2/3 divide 1 2/5

(there are a few more too but just this one for now!)

how horrible! hope his dad gets it sorted out for him.

He has to get the bus home, he can get a choiceof 2 buses so maybe he should use the other one. His dad works just down the road from him but he got a bit lost when running away from the boys tonight so didn't know the way there. He was really upset by the time he eventually got home. He said he thinks the boy is going to kill him The gang members are the same age, the so called leader is not in his class but is in some of his lessons.

When you are decomposing fractions you are supposed to look for the highest common multiple of the numerator and the denominator and work down both the top line and the bottom.

So when Philipat came out with 70/21 then you should spot that 7 is the highest common multiplar of both.

Divinding both top and bottom by 7 gives you 10/3, then an easier division gives you 3 1/3.

You would take the same approach to your other examples Kid.

how about this one

2 5/16 + 1 3/7

oh no I'm seriously gutted that I got the last bit wrong (not immediately dividing my 70/21 by 7). Ah well... that history of art degree was useless...

2 5/16 + 1 3/7

37/16 + 10/7

259/112 + 160/112

419/112

ok, someone else can reduce that

2

Dh says

3 41/61

Dh says

3 41/61

3 and third?

Which is nearly 3 2/3

tee hee

we have worked it out so far to 3 83/112 which you can't change to 41/61 can you?

DH said sorry he can't add 35 and 48 in his head!!!! He got 82/112.

tit

Philippat - when you are doing whole numbers and fractions, I think it is easier to just add the whole numbers (i.e. 2 +1=3) and then add the fractions, (5/16 +3/7 = 41/61) then add both together to give 3 83/112.

It saves you ending up with a huge fraction to decompose when you know what the whole numbers are anyway!

Dh agrees with soapbox!!!! Who obviously can add.

Oops sorry - the middle step was cribbed until I realised it was wrong - so final answer is right but middle bit should read 83/112

d'oh!

do hope your nephew has a better day tomorrow, kid. Did a bunch of virtual women helping with his homework make him feel better or worse?

I didn't tell him I was getting help on the internet , he must just think I am clever to know all the answers

well that will make him feel good, hopefully
