Step-by-step explanation:
We know the area of a circle is:

Answer:
2/3&1/6
2/3- 1/6
the LCM for 3 and 6 is 6
=(2x6)/(3x6) -(1x6)/(6x6)
=4/6-1/6
=(4-1)/6
find the difference
= 3/6
=1/2
2/3-1/6= 1/2
By using LCM method, 1/2 is the equivalent fraction by subtracting 1/6 from 2/3.
2/3&1/6
2/3- 1/6
cross multiply
2x6-1x3/3x6
simplify
12-3/18
=9/18
= 1/2
2/3-1/6 = 1/2
By using cross multiplication method, 1/2 is the difference between two fractions 2/3 and 1/6.
