Question

Find one terminating decimal and one repeating decimal between -1 1/2 and -1 7/9

Answer 1

-1.777...

Explanation:

Using the LCM of 18 for the denominator, these values are:

-1 7/9 -1 1/2

-32/18 -27/18 0

--------------|-------------------|-------------------------------------|-----------

So, the easy values to identify are: -31/18, -30/18, -29/18, and -28/18

All of these numbers have repeating decimals (because 9 is a factor of the denominator).

Now, you may realize that -1 3/4 is within the range specified.

-1 7/9 -1 1/2

-32/18 -27/18 0

--------------|-------------------|-------------------------------------|-----------

-1 3/4

-1.75

This is because -1.75 is between -1.5 and -1.7777.... Note that it is not repeating.
