Answer 1

Respuesta:

1° a) 6/8=(2•3)/(2•4)=3/4

b) 25/30=(5•5)/(5•6)=5/6

c) 12/20=(3•2•2)/(5•2•2)=3/5

2°

(3+½)+2•(1+¼)=(6/2+½)+2•(5/4)=

=(7/2)+(10/4)=(14/4)+(10/4)=24/4=6 kg

-La bolsa del mandado pesa 6 kg en total.

3°

(10+½)-(1+¾)=(20/2+1/2)-(4/4+¾)=(21/4)-(7/4)=

=14/4=(7•2)/(2•2)=7/2=3½ kg

-La pintura vinílica pesa 3½ kg.

4°

¼ de hora=¼•60min=60/4min=15min

¾ de hora=¾•60min=180/4min=45min

5°

200/500=(2•100)/(5•100)=2/5litros

6°

81/90=(3•3•3•3)/(5•2•3•3)=9/10

7°

5/10=1/2=0.5

8° a)0.006=6/1000=3/500

b)0.1=1/10

c)0.003=3/1000

d)0.056=56/1000=28/500=14/250=7/125

e)0.984=984/1000=492/500=246/250

=123/125

f)0.001=1/1000

g)0.4=4/10=2/5

h)0.17=17/100

i)0/5=5/10=1/5

j)0.08=8/100=4/50=2/25

Si algunos se pueden simplificar más, simplifícalo.
