Gabriella had 6/8 of a whole pie left she gave Reuben 2/3 of the pie she had left how much of a whole pie did Reuben get
Cloud [144]

Answer:

\frac{1}{2} of the whole pie

Step-by-step explanation:  

The problem calls for a <em>multiplication of fractions.</em> In order to know how much pie Reuben got, we have to multiply \frac{2}{3} by the pie Gabriella has, which is \frac{6}{8}.

So: \frac{2}{3} x \frac{6}{8} = \frac{12}{24}

Let's reduce the answer to its lowest term by dividing both the<em> numerator</em> and the <em>denominato</em>r by 12.

Numerator: 12÷12 = 1

Denominator: 24÷12 = 2

So, this makes Reuben's share being \frac{1}{2} of the whole pie.

Is a + b rational or irrational
enyata [817]

Answer and Step-by-step explanation:

It depends on the numbers that are inputted for a and b.

If the numbers that are inputted for both a and b are rational, then a + b would be rational.

If the numbers that are inputted for both a and b are irrational, then a + b would be irrational.

If one of the variables is rational and the other is irrational, then a + b would be irrational.
