# Readers’ cats: Fatty Boom Boom

My daughter’s cat made Why Evolution is True’s blog.

Here is a postprandial moggie with a strange name, replete with Thanksgiving bird and described by staff member Thaddeus Aid.

I just had to defend my turkey dinner from my daughter’s cat. It was a wild tale of the great white hunter stalking his prey. Thankfully my fully cooked bird did not succumb to his prowess.

Later all the cats got to share some of the leftover turkey. The d-g had to subsist on leftover steak.

The cat’s name is Fatty Boom Boom (my daughter named him through a series of names starting with Parsnip and Hashtag but ending with that, so we didn’t know what he was going to be called for a week or so). The photo is tonight, post hunt and noms.

The other cats are Monster (wife’s cat, named by my son when he was 4)…

This is for a friend who has a question about why one fraction equals another.

The question is why does $\frac{45}{-30}=\frac{-3}{2}$

Let us take this through the steps one at a time:

The obvious start is that the answer should equal itself to begin with:

$\frac{45}{-30}=\frac{45}{-30}$

By convention the negative sign should be on the top so we multiply both sides by $\frac{-1}{-1}$

$\frac{-1}{-1}*\frac{45}{-30}=\frac{-45}{30}$

Now we factorise -45 and 30, but we can think of -45 as $-1 * 45$ so we only need to factorise 45:

30 = {1, 2, 3, 5, 6, 10, 15}

45 = {1, 3, 5, 15}

The largest factor is 15 for each so we will use that for our reduction:

$\frac{-1*45/15}{30/15}=\frac{-1*3}{2}=\frac{-3}{2}$
