A 2/3=8/2. B. 4/9=8/9 c 3/4>9/10 d 2/4>2/3 which comparison is true

The given comparisons are not true in all of the options provided.

Step-by-step explanation:

The given comparisons are in the form of fractions.

Check each of the given options one by one based on the relation given for the comparison.

Option a) is 2/3 = 8/2. Here, you have to check that the given fractions are equal or not. If both the values are equal, then the comparison is true. If they are not equal, then the comparison is false.

By dividing 2 by 3, we get a value of 0.666

By dividing 8 by 2, we get a value of 4.

Therefore, 0.666 ≠ 4. The comparison is false.

Option b) is 4/9 = 8/9. Here, you have to check that the given fractions are equal or not.

Look into the given comparison, the fractions have same denominator of 9.

In such cases, if the denominator is same and the numerator value is different, then they are not equal.

Therefore, 4/9 ≠ 8/9. The comparison is false.

Option c) is 3/4 > 9/10. Here, you have to check whether 3/4 is greater than 9/10.

By dividing 3 by 4, we get a value of 0.75

By dividing 9 by 10, we get a value of 0.9

Therefore, 0.75 is not greater than 0.9. The comparison is false.

Option d) is 2/4 > 2/3. Here, you have to check whether 2/4 is greater than 2/3.

By dividing 2 by 4, we get a value of 0.5

By dividing 2 by 3, we get a value of 0.666

Therefore, 0.5 is not greater than 0.666. The comparison is false.
