Question

se dau numerele
a = 9 x 3
b = 56 : 7
c = 0 : 10

Calculeaza:

a - (b + c )=
(a x c ) : b=

Answer 1

a = 9 × 3

a = 27

b = 56 : 7

b = 8

c = 0 : 10

c = 0

________________________

a - ( b + c ) = 27 - ( 8 + 0 ) = 27 - 8 = 19

( a × c ) : b = ( 27 × 0 ) : 8 = 0 : 8 = 0

Answer 2

a=27
b=8
c=0
27-(8+0)=27-8=19
(27x0):8=27:8=3(rest3)
