Answer:

a) 28 flats

Step-by-step explanation:

A) Let the no. of flats be x

Lets take a proportion:

=> 7:4 :: 49 : x

Writing it in fraction form

=> [tex]\frac{7}{4} = \frac{49}{x}[/tex]

Cross Multiplying

=> 7x = 196

Dividing both sides by 7

=> x = 28 flats

B) I got the answer by simply taking the proportion.
