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]
