12a2/(2ab) = 6a/b
15b/39b4 = 5/13*b-3
The vertex is b and the rays are ba and bc.
Suppose A/B equals a decimal fraction F, which has d digits after the decimal place and then terminates.Then (A/B)*10D = F*10D is an integer.That is A*10D/B is an integer.A and B are coprime so they have no factor in common and therefore B must divide 10D.
in it's simplest form square root everything to get: a+b=8 i.e. a=8-b or b=8-a

12a2/(2ab) = 6a/b
7/24
(a + b)/(a - b) = (c + d)/(c - d) cross multiply(a + b)(c - d) = (a - b)(c + d)ac - ad + bc - bd = ac + ad - bc - bd-ad + bc = -bc + ad-ad - ad = - bc - bc-2ad = -2bcad = bc that is the product of the means equals the product of the extremesa/b = b/c
20 over 60 is the same as 2 over 6. And 2 over 6 is the same as 1 over 3. B-EHS
that is the simplest form b/c u cant divide 19 in half and have it be in whole numbers. why do u rely on other people to figure that out for u? u will FAIL in math if u do that
These are rational number that are not integers. In their simplest form, they are of the form a/b where a and b are integers and b is not 0 nor 1.
What do you want it solved for ?'s' ? or 'b' ? or 'c' ?Since this is the formula for the total effective resistance of two parallel resistors,the inductance of two parallel coils, and the capacitance of two series capacitors,as well as the "lensmaker's formula" that relates the image distance, object distance,and focal length of a lens, it's probably the most useful to solve it for 's', and I will nowdo so. I shall require total silence from members of the audience.1/s = 1/b + 1/cMultiply each side by 'bc':bc/s = bc/b + bc/cbc/s = c + bMultiply each side by 's':bc = s (c + b)Divide each side by (c + b):bc/(c+b) = sThis is the handy form that's easy to remember ... it's "the product over the sum".
You can not. That is already simplest form.
