Easy and Smart Math Fractions

One minute Easy and Smart Math Fractions a smart way doing fractions in mathematics, the first steps must be taken to know how to add or subtract fractions the same denominator. The second solution to know how to do fractions are not the same denominator by equating the denominator first.
The third solution to know how to do mixed fractions (Mixed rational number) we will further discuss how intelligent the problem mentioned above, we will start one by one with a smart and easy way.

Addition Same Fraction Denominator
  • 1/3 + 2/3 = 3/3 = simplifies to 1
  • 2/8 + 3/8 + 1/8 = simplifies to 6/8 = 3/4
  • 7/9 - 2/9 + 5/9 = 10/9 =  simplifies to11/9

The addition of Mixed fraction denominators are not the same
  • 1/3 + 2/4 = 3/12 + 6/12 = 9/12  simplifies to 3/4
  • 21/3 + 32/4 = [ 2 + 3 ] 3/12 + 6/12 = 59/12 simplifies to 51/4
Equating Denominator ( 3 × 4 = 12 )
Easy smart math method (12 : 3 × 1 = 3 and (12 : 4 × 2 = 6) next (numerator + numerator)
for about the same fractional reduction in the denominator or not the same way except that the numerator minus the numerator is valid for mixed fractions, but does not apply to multiplication and division of fractions.

Multiplication of mixed fractions 
  • 2/4 X 3/5 = 6/20 simplifies to 3/10
  • 32/4 X 43/5 = 14/4 X 23/5 = 322/20 simplifies to 161/10
Note : FIRST mixed fractions change be fractions this way ......
32/4 = [ 3 X 4 ] + 2 = 14/4 and  43/5 = [ 4 X 5 ] + 1 = 23/5


Division of mixed fraction

  • 1/2 : 2/5 = 1/2 X 5/2 = 5/4 simplifies to 11/4 
  • 31/2 : 32/5 = 7/2 : 17/5 = 7/2 X 5/17= 35/34 simplifies to 11/34
Note : FIRST mixed fractions change be fractions and last fraction the numerator over the denominator under.
After flipping the numbers (numerator and denominator to the numerator to the denominator) then multiplied (the numerator and denominator to the numerator by the denominator)

Have you could use this method? if you do not watch and read way back twice if you could surely can not repeat again reading way equate the denominator and producing an own questions and do over and over until you can with practice may be more substantial and always practice continues because mathematics need to practice and try so that the results are very good. Find about the different models and can certainly do.
examples of math story
