For a science project, Mrs. Gaston's science class is recording the growth of their blue iguana
at the end of every month. Her class uses a table like this:
________________
September inch 1/8

October 3 inch 3/8

November inch 5/8

December inch 1/8

1. How many inches had the blue iguana grown by the end of October?

2. How many inches had the blue iguana grown by the end of December?

3. If the blue iguana was 3 inches long by the end of September, how long was the
iguana at the end of August?

Answer:

I guess that the table is:

September (1 1/8) in

October (3 3/8) in

November (1 5/8) in

December (1 1/8) in.

1) by the end of October, the iguana has grown:

D = (1 1/8)in + (1 5/8)in + (3 3/8)in = 5in + (1/8 + 3/8 + 5/8) = (6 1/8) in.

2) How many inches had the blue iguana grown by the end of December?

Here we add the other (1 1/8)in to the number that we find above:

(6 1/8)in + (1 1/8)in = 7in + (1/8 + 1/8)in = (7 2/8)in

3) the iguana is 3 inches long at the end of September, then at the end of Agust, the length of the iguana is x = 3in minus the amount that it grows in December:

X = 3cm - (1 1/8)in = (1 7/8)in
