A rational number is any number that can be written as a ratio or a fraction.

So 5/9 is a rational number. So basically that eliminates 2, 3, and 4.

And we are left with 1. as our answer choice which is Rational and real.

Please help me with this question on algebra

The solution is option D.

0     4
- 6     1
3    -4

Rember rows times columns.

=>
a11 = 4*0 + 0*(-3) = 0

a12 = 4*1 + 0*1 = 4 + 0 = 4

a21 = -1*0 + 2*(-3) = 0 - 6 = -6

a22 = -1*1 + 2*1 = -1 + 2 = 1

a31 = -3*0 + (-1)*(-3) = 0 + 3 = 3

a32 = -3*1 + (-1)*1 = -3 - 1 = -4
