Question

2 - Assinale as alternativas corretas:
a. ( ) 100 x 2 = 10 x 5
b. ( ) 8 x 15 = 2 x 60
C. ( ) 20 x 4 = 10 x 8
d. () 30 x3 = 5 x 12
e. ( ) 50 x3 = 5 x 30​

Answer 1

a. (F) 100 x 2 = 10 x 5

b. (V) 8 x 15 = 2 x 60

C. (V) 20 x 4 = 10 x 8

d. (F) 30 x3 = 5 x 12

e. (V) 50 x3 = 5 x 30​

Explicação:

a) 100 x 2 = 200

10 x 5 = 50

200 ≠ 50

b) 8 x 15 = 120

2 x 60 = 120

120 = 120

c) 20 x 4 = 80

10 x 8 = 80

80 = 80

d) 30 x 3 = 90

5 x 12 = 60

90 ≠ 60

e) 50 x 3 = 150

5 x 30 = 150

150 = 150
