Answer:

Irrational

Step-by-step explanation:

A rational number can be expressed as a ratio of two integers , p and q of the form \[\frac{p}{q}\]

So following are examples of rational numbers:

  • \[\frac{1}{2}\] is a rational number
  • \[\frac{3}{4}\] is a rational number
  • 2 is a rational number as it can be expressed as \[\frac{2}{1}\]

On the other hand , any number which cannot be expressed in this form is called an irrational number. For example:

  • \[\sqrt{2}\]
  • \[\sqrt{3}\]
  • \[-\sqrt{127}\]

Chad can paint a room in 5 h. cassie can paint the room in 3 h. how long would it take them to paint the room working together?
Georgia [21]
If Chad can paint the whole room in 5 hours, in 1 hour he gets 1/5 of it painted.  If Cassie can paint the whole room in 3 hours, in 1 hour she gets 1/3 of it painted.  If we add those together we can find out how much of the room they can paint together in one hour.  1/5 + 1/3 = 1/x, with x being the number of hours it will take them to paint the room together.  Common denominator is 15, therefore, 3/15 + 5/15 = 1/x and 8/15 = 1/x.  Cross-multiply to get 8x = 15, so it will take them 15/8 hours, or 1.9 hours to paint the whole room together.
