Answer:
B; 2/3 < 5/7
Explanation:
Find a common denominator:
A common denominator is 21. Multiply the denominators by the number you need to get to 21. The common denominator would be 7 for 2/3 and 3 for 5/7.
x 7= 14/21
x 3 = 15/21
The statement would be 14/21 < 15/21 which is true. Therefore, your answer is B; the second statement from the top.
