Clasa a 7. Fac meditati..... Am nevoi.

Answer 1

0,75+75/100=100/75=20/15=4/3

-0,24=-24/100=-100/24=-25/6

75/1=1/75

-0,125=-125/1000=-1000/25 =-200/5=-40/1=-1/40

-3=1/-3

Answer 2

0,75 = 75/100 => inversul = 100/75 = 4/3

-0,24 = - 24/100 => inversul = -100 /24 = - 25/6

75 => inversul = 1/75

-0,125 = - 125/1000 => inversul = - 1000/125 = -8/1

-3 => inversul = - 1/3
