Expressing all the numbers as decimal.
7/9 = 0.7777
square root of 3 is 1.732
From least to greatest, we have -0.8, 7/9, 1.732
Divide
7/12 = <span>.583
We get answer: </span><span>D. .583</span>
0 × <span>0 = 0
0 </span>× <span>1 = 0
1 </span>× <span>1 = 1
Which means multiplication is closed under {0, 1}
</span><span>1 </span>÷ <span>1 = 1
0 </span>÷ <span>1 = 0
</span>
Division is not closed under {0, 1}
1 + 1 = 2
Addition is not closed under {0, 1}
0 - 1 = -1
Subtraction is not closed under {0, 1} either
So it's only A. Multiplication which is closed under {0, 1}
The second answer is correct.
