She can serve a total of 12 persons.
- Amount of cakes she bought = 3
- Number of piece of cake she planned to serve her guests = 1 quarter of the cake (otherwise expressed as [tex]\frac{1}{4}[/tex] )
Further Explanation
To determine how many guests she can serve, we have to complete the following steps:
Step 1:
We will divide the amount of cakes she bought (3) by the number of piece of cake she planned to serve her guests ( [tex]\frac{1}{4}[/tex] ) i.e. 3 ÷ [tex]\frac{1}{4}[/tex]
Step 2:
Since we are dividing a whole number (3) by a fraction ( [tex]\frac{1}{4}[/tex] ), we would need to do two things:
- We have to convert the division sign (÷) to multiplication (x) i.e. (÷) become (x)
- We have to exchange the places of the numerator and denominator of the fraction ( [tex]\frac{1}{4}[/tex] ) i.e. ( [tex]\frac{1}{4}[/tex] ) becomes ( [tex]\frac{4}{1}[/tex] )
Therefore, we have 3 x [tex]\frac{4}{1}[/tex]
Step 3:
We multiply the whole number (3) by the numerator of the fraction, and then divide the derived value by the denominator of the fraction.
Therefore we have (3 x 4) / 1 = 12
Step 1 to 3 joined together:
= 3 ÷ [tex]\frac{1}{4}[/tex]
= 3 x [tex]\frac{4}{1}[/tex]
= (3 x 4) / (1)
= (12) / (1)
= 12
