It would be -6/25, 7/3, 1.34, 2.4.
You would first convert all of this into one form. Since decimal is the most common one, we can convert the fractions into this. Divide the denominator by the numerator. -6/25 would be -4.2 (rounded to the tenth place) and 7/3 would be 0.4 (rounded to the tenth place). So, it would be 0.4, 2.4, -4.2, 1.34.
-4.2 would be the first because it is lesser than them all since it is less than zero, then 0.4 would be next, 1.34, and then 2.4. Just look back at the original problem to get -6/25, 7/3, 1.34, 2.4
