MGB: Math problem

I need some help with a math problem I am no good at math. If a rear end ratio is 3.78:1 and an overdrive is added, which is a 26% overdrive, what is the final ratio in overdrive? And how do you do that????

2.80 (rounded to two places). 3.78 x.74

Bill,

This explains in detail the calculations and the information you need to make the calculations.

Me brain hurts........

there are 7 girls on a bus, no driver, each girl has 7 backpacks, there are 7 large cats in each backpack,
for each large cat there are 7 small cats, how many legs are on the bus?
Thats a 5th grade math problem.
Yours is a bit easier. :eyeroll:

I'll bet one of the cats is an amputee just to mess with us.

none, busses don't have legs

Thanks for the replies. It is just morning, and already my head hurts. I have a vision in my head of a four legged bus walking down the road full of girls and cats.

A bus full of pussys?

Not a trick question! One of those 5th grader problems.
Doglegs dont count either (if a bus has those :S)

BTW Bill, I hope your question was answered B)

Joe got this one right on the first try.

3.78 times 0.26=.982 This is the amount that the final drive is going to be reduced.( Can be read as 26% of 3.78 is 0.982)

So, if you started with a 3.78 ratio, simply subtract the 0.982 from the 3.78 and you get the answer: 2.798. Round up to 2.8 if you wish.

No salt flats. The model A ford ( I have several) comes stock with 3.78:1. Mitchell makes a 26% overdrive. I have 3.54:1 in two of my cars, but was considering a 3.27:1 for the roadster pickup, and wanted to see how it would compare to the overdrive. It seems like it would work fine.
Sorry it was not an mg question, but I suspected the math problem would be better solved here, than on a Model A forum.

Yes, for sure. Mrs. Slocum comes to mind.

Are you implying that the model A boys ain't as smarts as the boys here.

You missed the legs on the cat's fleas.

I have my shoes off and I still can’t figure it out?

Here's the solution...

Each backpack holds 56 cats
7 x 7 = 49
49 + 7 =56

56 cats x 7 backpacks = 392 cats

392 cats x 7 girls = 2744

2744 cats x 4 legs each = 10,976

10,976 legs + 14 legs(7 girls) = 10,990

Right. And there would likely be more arguing over the results.
