- Rational Numbers
- Quotients of integrers Is
the greatest common
factor of numerator and the
denominator 1.
- Fundamental property of rational
numbers a/b * k/k = a/b*
- 36/54 = 2/3*18/18=2/3*
- Cross-Product test
a/b=c/d if a*d=b*c
- 36/54=2/3
36*3=108
54*2=108
108=108
- 36/54=2/3
36*3=108
54*2=108
108=108
- Cross-Product test
a/b=c/d if a*d=b*c
- 36/54 = 2/3*18/18=2/3*
- Fundamental property of rational
numbers a/b * k/k = a/b*
- Quotients of integrers Is
the greatest common
factor of numerator and the
denominator 1.
- Operations with rational numbers
- To realize the operation of
addition the two fractions must
be redrawn in a unit taht both
have in common, then add
numerator with numerator and
the same with denominator,
then the fraction simplifies
- 1/3+2/5=
5/15+6/15=
11/15
- Addition and Simplifying of fractions
- 1/3+2/5=
5/15+6/15=
11/15
- Multiplying of fractions
- Multiply the nominator
with th other and teh
same with denominator
- 1/2*2/5= 2/10
- Because 2 and 10 are
multiples of themselves
they can be simplified by
the same number taht is
2
- 2/10= 1/5
- 2/10= 1/5
- Because 2 and 10 are
multiples of themselves
they can be simplified by
the same number taht is
2
- 1/2*2/5= 2/10
- Multiply the nominator
with th other and teh
same with denominator
- Division of fractions
- To divide the fractions invert
the divisor and then multiply
- (7/8)/(1/4)=
7*4=28,
8*1=8 =
28/8
- (a/b)/(c/d) = ad/bc
- (a/b)/(c/d) = ad/bc
- (7/8)/(1/4)=
7*4=28,
8*1=8 =
28/8
