determine which system will produce infinitely many solutions. −4x 6y = 204x − 3y = −2 −2x 4y = 184x − 8y = −36 3x − 2y = 5−6x − 4y = −10 5x − 3y = 1215x − 9y = 24

Fluffy is 9 9/16 lbs

Whiskers is 9 7/8 lbs

Mr. Nibbles is 9.75 lbs

Let’s first convert the fraction 7/8 to compliment the fraction 9/16:

7/8 = 14/16

9 7/8 is now 9 14/16, which is heavier than Fluffy’s weight.

Now that we know that, let’s convert .75 into a fraction:

.75 = 3/4

Make 3/4 compliment the other fractions:

3/4= 12/16

Let’s look at the weights now:

Fluffy: 9 9/16 lbs

Whiskers: 9 14/16 lbs

Mr. Nibbles: 9 12/16 lbs

Having a common denominator for all fractions makes it easier to determine how big or small the numbers are.

So, the order from heaviest to least heavy is:

Whiskers, Mr. Nibbles, Fluffy
