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.
