Answer:

\frac{1}{10} of the fish are red guppies.

and \frac{9}{10} of the fish are not red guppies.

Step-by-step explanation:

Given: two-fifths of the fish in Gary's fish tank are guppies.

           One fourth of the guppies are red.

To find: What fraction of the fish in Gary's tank are red guppies? what fraction of the fish in gary's are not red guppies?

Solution:

Let the total number of fish in Gary's fish tank be <em>x</em>.

It is given that two-fifths of the fish in Gary's fish tank are guppies.

So, number of guppies in the Gary's fish tank is \frac{2}{5}\times x

Now, it is also given that One fourth of the guppies are red.

So, number of red guppies =\frac{1}{4}\times \frac{2x}{5}

=\frac{x}{10}

So, \frac{1}{10} of the fish are red guppies.

and 1-\frac{1}{10} =\frac{9}{10} of the fish are not red guppies.

Six boys are comparing their heights. Andy is taller than Dan but shorter than Ethan. Bill is taller than Ethan and Frank. Frank
Alexxx [7]

List of boys from tallest to shortest is: Bill, Frank, Ethan, Andy, Dan, Cory

<h3><u>Solution:</u></h3>

Given that Six boys are comparing their heights

The six boys are Andy, Dan, Ethan, Bill, Frank, Cory

To find: List the boys from tallest to shortest

<u><em>Andy is taller than Dan but shorter than Ethan</em></u>

So the arrangement goes like this:

Ethan

Andy

Dan

<u><em>Bill is taller than Ethan and Frank:</em></u>

So Bill is taller than ethan. Thus the arrangement from tall to short is made as:

Bill

Ethan

Andy

Dan

Also bill is taller than frank. So frank can be placed anywhere below bill

But given that Frank is taller than Ethan. So frank can be placed above ethan

Now the arrangement goes like this:

Bill

Frank

Ethan

Andy

Dan

<em><u>Cory is shorter than Dan.</u></em>

So cory can be placed below Dan.

<em><u>Thus final arrangement from tallest to shortest boys are:</u></em>

Bill

Frank

Ethan

Andy

Dan

Cory
