A group of friends share 3 1/2 slices of cakes each friend gets half a slice of cake how many friends shared the slices of cake ? Each whole slice of cake can be divided into _____( 3 halves,1 half,2 halves) so 3 1/2 slices of cake is a total of _____ ( 4 halves,7 halves,9 halves) because each friend gets half a life of cake there are _____ (9,7,4) friends

  Answer:

  Each whole slice of cake can be divided into 2 halves so [tex]3\frac{1}{2}[/tex] slices of cake is a total of 7 halves because each friend gets half a life of cake there are 7.

  Step-by-step explanation:

  Given : A group of friends share [tex]3\frac{1}{2}[/tex]  slices of cakes each friend gets half a slice of cake.

  To find : How many friends shared the slices of cake ?    

  Solution :

  According to question,

  [tex]3\frac{1}{2}=3+\frac{1}{2}[/tex]

  i.e. it divided into 2 halves.

  [tex]3+\frac{1}{2}=1+1+1+\frac{1}{2}=\frac{1}{2}+\frac{1}{2}+\frac{1}{2}+\frac{1}{2}+\frac{1}{2}+\frac{1}{2}+\frac{1}{2}[/tex]

  i.e. total [tex]\frac{1}{2}[/tex] slices are 7 halves.

  Each friend gets half a life of cake

  i.e. there are 7 friends.

  Rounding all the statements together,

  Each whole slice of cake can be divided into 2 halves so [tex]3\frac{1}{2}[/tex] slices of cake is a total of 7 halves because each friend gets half a life of cake there are 7.

  What are proper and improper fractions and how to convert mixed fraction to simple fraction?

  There is a fraction, containing numerator(upper value) and denominator(lower value).

  When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction.

  A proper fraction is also called fraction which is less than 1.

  And an improper fraction is ≥ 1

  A mixed fraction contains a sum of whole number and a proper fraction.

  One example of mixed fraction is

  [tex]a\dfrac{b}{c}[/tex]  

  It can be taken as

  [tex]a\dfrac{b}{c} = a + \dfrac{b}{c} = \dfrac{a \times c + b}{c}[/tex]

  Since it is given that there are in total [tex]3\dfrac{1}{2}[/tex] slices of cakes, we can convert it to normal fraction as

  [tex]3\dfrac{1}{2} = 3 + \dfrac{1}{2} = \dfrac{3 \times 2 + 1}{2} = \dfrac{7}{2} = 7 \times \dfrac{1}{2}[/tex]

  This shows the amount of slices of cakes.  It means there were 7 half slices of cake.

  Since each friend took half slice, and all of [tex]3\dfrac{1}{2}[/tex] slices was consumed, thus, there must be 7 friends in the group.

  Thus,

  The completed statement is

  Each whole slice of cake can be divided into ___2 halves__( 3 halves,1 half,2 halves) so 3 1/2 slices of cake is a total of ___7__ ( 4 halves,7 halves,9 halves) because each friend gets half a life of cake there are __7___ (9,7,4) friends
