Question

Gasiti numerele care fac posibile impartirile:
a) ( 20 + 32 : 8 x 9 ) : x =
b) ( 60 : 10 x 9 - 30 ) : x =

Answer 1

( 20 + 32 : 8 x 9 ) : x =
(20 + 36) : x =
56 : x =
x poate fi 1, 2, 4 , 7 , 8 , 14 , 28 , 56

( 60 : 10 x 9 - 30 ) : x =
( 54 - 30 ) : x =
24 : x =
x poate fi 1 , 2, 3, 4, 6, 8, 12, 24

Answer 2

a) (20 +32:8x9 ) :x =
( 20 + 4 x 9 ) : x =
( 20 +36 ) :x = 
56:x = >x = {1 2 4 7 8 }
b) ( 60 : 10 x 9 - 30 ) : x =
( 6 x 9 - 30 ) : x =
(54-30) : x =
24 : x => x {1 2 3 4 6 8 }
