Let's first have a look on rules to rationalize the given number containing root in denominator side..

Let's follow the rule and start it:-

Step 1: To rationalize the denominator, you must multiply both the numerator and the denominator by the conjugate of the denominator.

Remember to find the conjugate all you have to do is change the sign between the two terms.

Step 2: Distribute both the numerator and the denominator. Remember that you can multiply numbers outside the radical with numbers outside the radical and numbers inside the radical with numbers inside the radical.

Step 3: Reduce the fraction, if you can.

Answer:-

$4 \div 8 - \sqrt{4 } \\ \\ 4 \div 8 - 2$

HERE,√4=2

$4 \div 6$

$2 \div 3$

$answer = 0.67$
