Answer:   [tex]2\dfrac{3}{4}[/tex]

Step-by-step explanation:

Let x denotes the weight of puppy at the age of 2  months.

Given :At the age of 4 months, a puppy’s weight is 275% of its weight at the age of 2 months.

Since we can write 275% = 2.75  [ To convert percent into decimal we divide it by 100]

i.e. :At the age of 4 months, a puppy’s weight is 2.75x

Now, the number of times heavier is the puppy at 4 months than at 2 months will be :-

[tex]n=\dfrac{\text{Weight of Puppy at 4 }}{\text{Weight of Puppy at 2}}\\\\=\dfrac{2.75x}{x}=2.75[/tex]

In fraction , [tex]2.75=\dfrac{275}{100}[/tex]

To simplify , divide numerator and denominator by 11 , we get

[tex]=\dfrac{11}{4}=2\dfrac{3}{4}[/tex]

Hence, the puppy is [tex]2\dfrac{3}{4}[/tex] times heavier than at 4 months than at 2 months.
