In minutes it is 1500 min because if you just multiply 25 and 60 it equals 1500. I got the 60 from 60 sec. in one minute.
2.99
2 is a whole number
0.99 = 99/100
your fraction is:
mixed number = 2 99/100
improper fraction = 299/100 (multiply whole number to denominator & then add numerator)
hope this helps
I think the first one is a simple as it gets
for the second one it could be simplified to 6x^6-4 because u combine the x terms and distribute the power
