Question

Whiskers the cat weighs 3 1/2 kg and Pilglio weighs 5 kg. How many times as heavy as pilglio is whiskers? How many times as heavy as whiskers is pilglio?

Answer 1

Given:

Whiskers the cat weighs
`3(1)/(2)` kg and Pilglio weighs 5 kg.

To find:

How many times as heavy as pilglio is whiskers?

How many times as heavy as whiskers is pilglio?

Solution:

We have,

Weight of cat (whiskers) =
`3(1)/(2)` kg

=
`(3(2)+1)/(2)` kg

=
`(7)/(2)` kg

= 3.5 kg

Weight of pilglio = 5 kg

Now,

`(Whiskers)/(Pilglio)=(3.5)/(5)=0.7`

Therefore, whiskers is 0.7 times as heavy as pilglio.

`(Pilglio)/(Whiskers)=(5)/(3.5)`

`(Pilglio)/(Whiskers)=1.428571...`

`(Pilglio)/(Whiskers)\approx 1.43`

Therefore, piglio is about 1.43 times as heavy as whiskers.
