Question

0,5-1/2×(3/4-0,25)

Detaliat va rog

Answer 1

0,5 - 1/2 ori ( 3/4 - 0,25 )

5/10 - 1/2 ori ( 3/4 - 25/100 )

5/10 = simplifici prin 5 = 1/2

25/100 = simplifici prin 25 = 1/4

1/2 - 1/2 ori ( 3/4 - 1/4 )

1/2 - 1/2 ori 2/4

1/2 - 2/8

amplifici 1/2 cu 4

4/8 - 2/8 = 2/8 = 1/4 = 0,25

Answer 2

0.5-1:2×(0.75-0.25)

0.5-0.5×0.5

0.5-0.25

0.25
