Isaiah is completing a math problems and the last step: 25-28 1/5. what is the answer, show your work

First you have to make the numbers have the same denominator. To do so 25 turns into 125/5 and 28 1/5 turns into 141/5. Now you can subtract 125 and 141 and you get -16 then you put the 5 under so it's -16/5 and simplify th that and is you get -3 1/5. Hope that helps you . If it did please click the thanks button. If you have any questions then please ask them.

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )

Sorry can't answer that question
