Fraction regulations: ADDITION/SUBTRACTION OF FRACTIONS same Denominator: purely upload/subtract the numerator and reproduction the denominator. Ex. a million/2 + a million/2 = 2/2 or a million diverse Denominator: discover the best effortless factor of the denominator first. Then divide gcf by ability of each and every denominator and multiply the quotient by ability of its numerator. Then upload/subtract the products by way of fact the hot numerator. Ex. 3/4 + a million/6 = (9 + 2)/ 12 = 11/12 3/4 - a million/6 = (9 - 2)/12 = 7/12 MULTIPLICATION OF FRACTION purely multiply the two numerators and the two the denominators. If the product could be simplified, do it. Fractions might desire to be on their least difficult type. branch OF FRACTIONS Multiply the numerator to the Inversed Denominator. Then persist with the concepts in multiplying fractions.

(x/3+3/4)(3x/4-3/5)
=x/3*3x/4+x/3*-3/5 +3/4*3x/4 + 3/4*-3/5
=3x to the power 2/12 -3x/15 + 9x/16 -9/20
=3x to the power 2/12 (-3x*16+9x*15)/550 -9/20
=3x to the power 2/12 (-48x + 135x/550)-9/20=Ans.
It's very difficult so first write it in a copy in a numerical form and then you will get it easily.
Best of luck!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
