There is always a value that will change number x into number y (unless x=0). Form the multiplier thus
So for 12 ---> 60 use 60/12 = 5 and for 9 ---> 60 use 60/9 = 20/3
I know I may be missing something. You strictly took theand instead of finding a number which multiples into it, to make you did ?
method 1. Start by adding the fractions using the usual rules. This leads to something/96. Simplify to something/24.
To change /24 into /60 you need to multiply top and bottom by 2.5 This gives a fraction with a denominator of 60. Split off 5/60 and whatever numerator is left is the required answer.
Without giving the answer, I didn't understand your explanation ?
Correct me if this is wrong, this is what I read;
You can find the lowest common denominator by finding what 3 and 7 will multiple by evenly ?
That leaves a remainder, since nothing will multiple byto get . Therefore one can't use as the lowest common denominator, one must use , correct ?
In other words, when you have found the lowest common denominator and you know the number which you used to find the lowest common denominator. You then simply multiple the numerator (and denominator) of the number you used to find the lowest common denominator for the first fraction, correct ?
Then you use the result of the answer for the numerator as in the case for the three over thirty-five for the first fraction ?
For the first fraction you have to multiple the numerator and the dominator by what you got to get 35. Before I go any further into adding the fraction by making the lowest common denominator; here is the fixed fraction.
I assume I put the result of 3x7=21 for the first fraction ?
Anyone here understand how a cross product works in relation to 3D ? I understand the core of what it does which is the third vector from the other two vectors but relating that to 3D space has been the issue. Here is my theory of how it works, suppose you have a sphere and a plane in a scene, the sphere is traveling on the Y axis, that is one vector, the plane is static, which is another vector, the X axis. When the sphere touches or hits the plane, the cross product would be the axis or vector to the right of the sphere and plane, suppose that is behind the sphere, when the sphere touches the plane, it will create a red mark which is the cross product of the sphere and the plane ?
Is my theory somewhat correct, or completely wrong ?
We represent a complex number in XY plane. real part is along or parallel to X axis and imaginary part is along or parallel to Y axis.e.g. Let us say you represent a land map as complex plane.say village B is x+jy distance from village A. x is distance along east ( displacement to west considered -ve)and y along north. You can cover the distance by 3 sessions of drive say. a+jb, c+jd, e+jf Thenat the same distance.
Real and imaginary parts must separately balance on both sides.
i.e. x=a+c+e and y=b+d+f If both are not satisfied you will not reach B.
If there is a village C such that AC=j(x+jy) ,C will be located such that
You're going to have to give a simpler example, until I can wrap my head around it ?
usually mathematicians use i and engineers use j . Both mean the same thing. 4+5i is represented by distance 4 along x axis and distance 5 parallel to y axis.You can say an "i" attached with a number rotates the vector by 90^0.
interestingly 4 i^2 means vector 4 along x axis is rotated by 180^0 and becomes -4 . this tallies with the concept that i^2=-1.
What if I write a formula 34j, what is that, literally, besides the number 34 ?
