6.25=25/4
4(1/8)=25/4
6.4=25/4
6(2/8)=25/4
4(1/4)=25/4

Answer 1

Answer: 6.25 = 25/4 and 6 2/8 are both correct.

Explanation:
To find if the first equation is true, divide 25/4 in your calculator and you will get the answer of 6.25.

All of the answer choices after that are set to equal to 25/4. To find if the other answer are true, we can use what we found from the first equation and use it as a comparison.

Get 4 x 8 + 1, then divide the product by the denominator, 8. The answer is 4.125 which is not equivalent to 25/4.

We know that the third option is incorrect because we proved what 25/4 equals to in the first option.

Get 6 x 8 + 2, then divide the product by the denominator, 8. The answer is 6.25 which is equivalent to 25/4.

Get 4 x 4 + 1, then divide the product by the denominator, 4. The answer is 4.25 which is not equivalent to 25/4.

Hope this helps.
