Answer:

-0.34, -0.35, -0.36, -0.37

Step-by-step explanation:

A rational number can be any number, negative or positive, so long as if the decimals (if any) terminate at some point or at least repeats itself.

-\frac{2}{5} = -0.4

-\frac{1}{3} = -0.333_ (This means that the digit "3" is repeated forever)

Thus, the possible rational numbers can be:

-0.34

-0.35

-0.36

-0.37

-0.38

-0.39

You can even write decimals like -0.334 since it is bigger than -0.333_ but smaller than -0.4.

Answer:

a.) The sum of the weights of the two in insects is 0.0031 grams. (0.0031 grams)

b.) The fly is 0.0013 grams heavier than the gnat. (0.0013 grams)

Step-by-step explanation:

2.2 * 10^-3 = 2.2 * 1/1000 which is 2.2/1000.

9 * 10^-4 = 9 * 1/10000 = 9/10000

To add 9/10000 to 2.2/1000 we have to find the common denominator, which will be 10000.

So we do:

2.2/1000 * 10/10 = 22/10000

9/10000 + 22/10000 = 31/10000 = 0.0031.

The sum of the weights of the two in insects is 0.0031 grams.

To find how much heavier the fly is than the gnat we do:

22/10000 - 9/10000 = 13/10000 = 0.0013

The fly is 0.0013 grams heavier than the gnat.
