At the age of 4 months, a puppy’s weight is 275% of its weight at the age of 2 months. how many times heavier is the puppy at 4 months than at 2 months? write your answer as a mixed number in simplest form.
If we let x be the puppy's weight from the past two months, and that the weight after 4 months is 2.75x.
The mixed fraction relating the weight of the puppy after 4 months and after 2 months is,
2 3/4.
Answer: \(2\dfrac{3}{4}\)
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 :-
\(n=\dfrac{\text{Weight of Puppy at 4 }}{\text{Weight of Puppy at 2}}\\\\=\dfrac{2.75x}{x}=2.75\)
In fraction , \(2.75=\dfrac{275}{100}\)
To simplify , divide numerator and denominator by 11 , we get
\(=\dfrac{11}{4}=2\dfrac{3}{4}\)
Hence, the puppy is \(2\dfrac{3}{4}\) times heavier than at 4 months than at 2 months.
