Quick answer

Any irrational number. I can't think of any exception to this statement.

sqrt(5) is irrational. 1/2 * sqrt(5) is still irrational.

-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational

2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.

1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.

Conclusion

There are no exceptions to this. All irrational numbers produce irrationals when multiplied by 1/2

Answer:

Divide 3/4 by 3/5 to get 1 1/4.

Step-by-step explanation:

To find area, you multiply the length by the width. However, they gave you the area and the width. Therefore, you divide the width by the area (I think).

3/4 divided by 3/5 = 1 1/4

The length is 1 1/4.
