I'll try. Here is another example
So another example I have is nx8x3=48, so:
... ? x 8 x 3
... =24
... ? x 24
... =48
So answer is 2 but I'm not allowed to say what x 24=48 because it involves using the 12 times table and I can only go up to the 10 times table.
Thanks:)
Hi
I have some basic multiplication question: ?x3x10=150
I know the answer is 5. I know that I can divide 150 by 10 and get 15 and then divide that by 3 to get 5.
However, I have to work this out without using mental arithmetic or division. I have to use a a pyramid to get the answer. However, it needs to be down to the lowest numbers. For example. For the sum above, I have to do this:
nx3x10
3x10=30
5x30=
150
n=5
However, I am not allowed to do the sum at this level. I have to find a way of breaking down the sum 5x30=150 so that I'm using numbers up to 10 only so basically, I need to arrive at the answer 5 using lower numbers than 11. I am not allowed to use division.
Any ideas?
Just to confirm. Removing zeros isn't going to work as not all the sums have zeros to drop...
Thanks:)
Oh thank you so much!
So on that basis, is the person getting GBP to BRL still off than the person getting GBP to USD? The % is lower but the difference between the 2 is higher. I need a penny to drop here!
Hi
I'm having real problems with something. I'm trying to work out % of decrease in value of 3 currencies against the British Pound as follows:
BRL USD EU
USD 5/3/07 4.1319 1.9455 1.4790
USD 5/3/09 3.3769 1.4075 1.1221
% drop 18% 28% 24%
I can't work out why the BRL, which made the biggest loss, is showing the lowest %. I must be using the wrong formula to work out the percentages (I'm dividing the 09 figure by the 08 figure).
I expected the BRL to have the highest % drop but it's the lowest.
Can anyone see what I'm doing wrong?
It's driving me nuts!
Thank you
