I'm going to re-post again but without the rest of the question to avoid any confusion.
I'm doing long division and I have 7296/577 . I go through the long division process and I get a quotient of 12 with a remainder of 372. If I were to use the calculator, the answer is 12.64 or just 12.6 for simples. My question is, how do I get/find this .4 that is on the end of the 12?
Well this very last one I cheated and used a calculator!!
But before I was doing it in my head.
well I'm practicing for an aptitude test where I have to do about 75 questions in 24 minutes. I am given a ball part with these kinds of questions to work with so I think the method I used is quite accurate.
Okay, sounds good. Speed is good sometimes.
So now are you going to find out how much time it took for them to meet?
And then take that time and multiply it by the slower A rate for the distance,
supposing they are approaching each other in opposite directions...??
pretty much. So it's 4.3 x 264 =1135.2 so 1135. We just assume aircraft or A is traveling towards B. We don't worry about which is faster or slower unless it says Where (distance from the startpoint of vehicle B) will both vehicles meet?
If you want you can bring down the invisible zero and keep dividing.
So you get 1960 divided by 588, and then pick 3, and go
around and around getting the same answer again and again,
bringing down a zero.
sure can!, but I'm trying to do the question in under or as close to 30 seconds as I can by hand.
Oh, I see it now!!
196 times 3 is 588, so 1/3 = 0.3333333333333333 forever.
So the answer of the division is 4.3333333333 repeating.
yes its recurring. So once I do all the long division and I get like a 4. something and I have a reminder, I divide the remainder by the divisor and get my decimal point. very nice
Since rate times time is distance, it is a linear equation, a line, distance on vertical y-axis,
rate or time, you pick it is on the x-axis, horizontal to the right.
This straight line means you can do reciprocals!! I don't know why I
know this, but the answer must be:
Distance of A =[ 324 / ( 324 + 264) ] times 2548.
Don't ask me how I know this, I just do... I'm old, 45 + or - 5 years.
Hi Thanks for the input but it's still a little off. You working got 1404 or 145.46 I cant remember while the answer is 1144, so it's almost in the ball park.
Hi all, I have a question to do with long division. My question is what do I do with the remainder?
Vehicle A and vehicle B are 2548 miles apart and move towards each other.
The speed of vehicle A is 264 mph and the speed of vehicle B is 324 mph.
Where (distance from the startpoint of vehicle A) will both vehicles meet?
Now thats where I stuff up somewhere. I use long division and I get quotient of 4 with a remainder of 196; I know the answer is going to end up as 4...something and then I need to multiply that by 264 but I don't know how to figure what comes after the 4. Please help! I know it's very basic math but I am always getting stuck at this part.
That is what you have? To solve it you would take the cube root of both sides first:
Now you just have a quadratic to solve. Using inspection you can see that one root is x = 2. Can you get the other?
Or are you trying to expand that out?
From the last step you have there I did:
x^2 - 1 = 3
X^2 = 3+1
X^2 = 4
x= root 4
I know it should be 2,-2 but how do I get the negative 2?
Hi, I was wondering what is the best methods to go about solving these perticular fraction questions. The questions are as follows..
What is 5/6 of 360?
What is 9/8 of 200?
What is 3/8 of 128?
Add 3/4 of 216 to 3/5 of 75
What is 12/16 expressed as a decimal?
Deduct 4/7 of 49 from 100
I'm ok with fractions but I have no idea how to go about with these types of questions. If someone could explain the best method to complete these questions it would be fantastic.
What is 267 divided by 3?
Divide 126 by 14
Much the same with these types of question, just what is the quickest methods to solve these. Thanks!
I'm brushing up on my 'simple' maths before I go a do a placement test and I know for a fact that there are a number of questions that ask for a percentage of a number or quantity of something. I was wondering if I can have some tips on how to do these types of questions in my head or any 'tricks of the trade' if any.
The structure and style of questions asked are as below.
Find 25% of 5 hours.
Find 45% of 70 meters.
Find 5% of $5
Thanks for the help:D
