Question

60.Efectueaza scaderile urmatoare : 12/10 - 7/10 = 5/9 - 2/9 = 7/2 - 5/2 = 25/10 - 14/10 = 100/10 - 54/10 = 67/100 - 17/100 = 9/100 - 8/100 = 101/100 - 11/100 = 97/100 - 47/100 = 125/100 - 35/100 = 194/100 - 99/100 =

Answer 1

Răspuns:

Explicație pas cu pas:

12/10 - 7/10 = ( 12 - 7)/10 = 5/10 = 1/2

5/9 - 2/9 = ( 5 - 2) / 9 = 3/9 = ( 3:3)/(9:3) = 1/3

7/2 - 5/2 = (7-5)/2 = 2/2 = 1

25/10 - 14/10 = (25 -14) / 10 = 11/10

100/10 - 54/10 = (100 -54) / 10 = 46/10

67/100 - 17/100 = (67 - 17) / 100 = 50 /100 = ( 50:50)/(100:50) = 1/2

9/100 - 8/100 = (9 - 8) / 100 = 1/100

101/100 - 11/100 = (101 - 11 ) / 100 = 90/100 = ( 90 : 10 ) / (100:10) = 9/10

97/100 - 47/100 = (97-47 ) / 100 = 50/100 = (50:50)/(100:50) = 1/2

125/100 - 35/100 = ( 125 - 35 ) / 100 = 90/100 = 9/10

194/100 - 99/100 =( 194-99)/100 = 95/100 = ( 95:5)/(100:5) = 19/20
