Question

Simplifique pelo método do mdc:

A) 84/72
B) 54/90
C)98/28
D)147/189
E)63/105
  

Answer 1

a)
mdc(84,72)=12

$\frac{84:12}{72:12} = \frac{7}{6}$

b)
mdc(54,90)=18

$\frac{54:18}{90:18} = \frac{3}{5}$

c)

mdc(98,28)=14

$\frac{98:14}{28:14} = \frac{7}{2}$

d)
mdc(147,189)=21

$\frac{147:21}{189:21} = \frac{7}{9}$

e)

mdc(63,105)=21

$\frac{63:21}{105:21} = \frac{3}{5}$

Answer 2

Resposta:

mdc (84/72)   = 12

84/12 = 7

72/12 = 6

7/6

mdc (54/90)   = 18

54/18 = 3

90/18 = 5

3/5

mdc (98/28)   = 14

98/14 = 7

28/14 = 2

7/2

                          mdc (147/189)   = 21

                           147/21 = 7

                          189/21= 9

                          7/9
