Answer 2

Oie, Td Bom?!

a)

= 37/100

= 37%

b)

= 13/50

= 13/50 . 2/2

= [13 . 2]/[50 . 2]

= 26/100

= 26%

c)

= 3/25

= 3/25 . 4/4

= [3 . 4]/[25 . 4]

= 12/100

= 12%

d)

= 2/5

= 2/5 . 20/20

= [2 . 20]/[5 . 20]

= 40/100

= 40%

e)

= 17/20

= 17/20 . 5/5

= [17 . 5]/[20 . 5]

= 85/100

= 85%
