Question

Calculaţi câtul b : a , dacă :
a = (290 -- 218 ) : 9 + 48 -- 248 : 8
b = 6 x 5 x 0 + 50 -- 5 x 10 + 0 : 8

Answer 1

a=(290-218):9+48-248:8
=72:9+48-31
=8+48-31
=56-31
=25

b=6×5×0+50-5×10+0:8
=30×0+50-50+0
=0+0+0
=0

a:b=25:0=0

Answer 2

a=72:9+48-31
a=8+17
a=25




b=0+50-50+0
b=0




a:b= 25:0=0
