Answer:
20 cakes
Step-by-step explanation:
Given
28 cakes in 7 days
Required
Determine the number of cakes in 5 days
Represent the required with x. The question illustrates proportionality.
First, we need to represent the given and required as a ratio
[tex]28 : 7 = x : 5[/tex]
Convert ratios to fraction
[tex]\frac{28}{7} = \frac{x}{5}[/tex]
[tex]4 = \frac{x}{5}[/tex]
Solve for x
[tex]x = 4 * 5[/tex]
[tex]x = 20[/tex]
