How would you rationalise this denominator?
1+√3/ √12
1+√3/ √12
Multiply both the numerator and denominator by root12 or root3
To rationalise a fraction, you want to make the denominator a whole number.

What would you do with the 1?

What would you do with the 1?
If you multiply the denominator of a fraction by a certain quantity, what do you need to do to the numerator to ensure that you end up with an equivalent fraction?

Let's go with another example:
(blah + whatever)/root2
= ((blah + whatever)/root2) *(root2/root2) = root2(blah + whatever)/2
Question you should ask yourself:
•
If root2/root2 is multiplied to the fraction, has the quantity changed? Why?
•
Have you rationalised the denominator? If so, have you achieved your goal?
1 is the same as 1/1
1 is the same as 2/2
1 is the same as 2/2
