Remember that: irrational numbers repeat and cannot be put into fractions.
1) C or 1/2, <em>Since it is expressed as a fraction you know it is rational. </em>
2) D or sqrt 61, <em>Well, it's not -5 since it's a whole number, basic multiplication tells you the square root of 36 is 6 which is also a whole number, and 2/3 is a fraction, so using process of elimination this is the only option left. </em>
3) quotient <em>Since rational numbers can be written as fractions, 1/4 is the same as dividing 1 by 4.</em>
4) repeat <em>As explained earlier, repeating decimals cannot be made into fractions, therefore not making them rational. </em>
5) 0.375 <em>3 divided by 8 is equal to 0.375. </em>
<em>I hope this helped you and have a great rest of your day! </em>
