tolong jawab nya saya butuh bangetttttttttttt pakai jalanya

1a) 3/5 = 3/5 x 2/2 = 6/10 = 0-6
B) 1/4 = 1/4 x 25/25 = 25/100 = 0,25
C) 1 1/4 = 5/4 = 5/4 x 25/25 = 125/100 = 1,25
d) 2 1/5 = 11/5 = 11/5 x 2/2 = 22/10 = 2,2
2) a) 6% - 1/6 + 0,52
= 6/100 - 1/6 + 52/100
= 58/100 - 1/6
= 0,58 - 0,166
= 0,414
B) 2 1/2 + 1/4 ; 3/2
= 2 2/4 + 1/4 : 3/2
= 2 3/4 : 3/2
= 11/4 : 6/4
= 11/6
= 1 5/6
