b) 1/2 - 1/6 =
c) 5 x 3/10 =
d) 4/6 + 1/3 =
e) 7/10 - 1/10 =
f) 7/5- 4/10 =
g)2/5 x 2/4 =
h) 11/12 - 1/6 =

Answer 1

Resposta:

a)3/2 x 1/6=3*1/2*6=3:3/12:3= 1/4

b)1/2 - 1/6=6-2/12=4:4/12:4= 1/3

c)5 × 3/10=5/0 x 3/10=5*3/0*10=15/0=15:5= 3

d)4/6 + 1/3=4+1/6+3= 5/9

e)7/10 - 1/10=70-10/100=6ø/10ø=6:2/10:2= 3/5

f)7/5 - 4/10=70-20/50=5ø/5ø=5:5/5:5= 1

g)2/5 × 2/4=2*2/5*4=4:4/20:4= 1/5

h)11/12 - 1/6=66-12/72=54:6/72:6=9:3/12:3= 3/4
