Answer:
14/21
Explanation:
14/21 is the correct answer because
We need to find the LCM or least common multiple between the denominator of 2/3 (which is 3) and 21.
The least common multiple between 3 and 21 is 21. This is because 21 is a multiple of 3.
21/3= 7
Both the numerator and denominator of 2/3 needs to be multiplied by 7 which gives a value of 14/21.
2×7= 14
3×7= 21
