Feeling totally demoralised and beaten.. Help!

Hey guys, I took my 2nd GMAT paper today and really hit the deck with it - in fact I have both times! The first paper I scored 370 - this mortified me as my practices had NEVER been this low. Today I scored 410. This time, the feelings were no way near as emotional, lets say! But as my score came on...

The ratio of w to x is 5 to 4. The ratio of x to y is 8 to 1. If the ratio of y to z is 1 to 3, what is the ratio of w + x to z ? 6:1 8:1 10:1 24:1 30:1 Like fractions, ratios can be MULTIPLIED: w/ x * x/y * y /z = w/z. In the equation above, all of the values in red CANCEL OUT, leaving only w/z. P...

Hi macattack Thanks for your help! I'm assuming W:X 5:4 we double to make more manageable? And in terms of combining do you mind quickly debriefing? Please excuse if none of this makes sense! But on reading again, I see that W:X and X:Y have 4 & 8, so is this the reason we've doubled W to make 1...

The format hasn't allowed my workings to be posted properly! The numbers are spaced correctly under each letter.

W : X
5 : 4

X : Y
8 : 1

Y - Z
1 : 3

The ratio of w to x is 5 to 4. The ratio of x to y is 8 to 1. If the ratio of y to z is 1 to 3, what is the ratio of w + x to z ? 6:1 8:1 10:1 24:1 30:1 I wrote out my ratios as so..

Congratulations, and thanks for such an inspirational debrief.

It's posts like these that keep me pushing!

Good luck in everything you apply yourself to.


Found the strategic reasoning really useful! For me, it made the workings out a lot more straight forward.

I just hope that when it comes to test day I see the stratgic routes too! :!: :!: :!:

Hi melguy,

Your response is most appreciated! I see the strategy behind it now, and certainly didn't think to recognise the repeating 5!

Many thanks again! :D

I've got this question right, but I'm not sure how!!

Hi there, I've been doing some practice tests, and this question has just cropped up. When 4/7 is expressed as a decimal, what is the 38th digit to the right of the decimal point? 8 7 5 3 1 I choose answer B - 7 as a strategic guess, fortunately it's correct! But I can't see how I could do the math ...
