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 heav
enyata [817]

Given:

Whiskers the cat weighs 3\dfrac{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\dfrac{1}{2} kg

                      = \dfrac{3(2)+1}{2} kg

                      = \dfrac{7}{2} kg

                      =  3.5 kg

Weight of pilglio = 5 kg

Now,

\dfrac{Whiskers}{Pilglio}=\dfrac{3.5}{5}=0.7

Therefore, whiskers is 0.7 times as heavy as pilglio.

\dfrac{Pilglio}{Whiskers}=\dfrac{5}{3.5}

\dfrac{Pilglio}{Whiskers}=1.428571...

\dfrac{Pilglio}{Whiskers}\approx 1.43

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