Question

calculati in doua moduri respectand modelul dat : (18+45):9=7=18:9+45:9=2+5=7

a)(27+54):9 (56+16):8

b)(48+24):8 (49+21):7

c)(36+45):9 (48+12):6

Answer 1

a)(27+54):9 = 27:9+54:9= 3+6= 9
(56+16):8= 56:8+16:8= 7+2= 9

b)(48+24):8= 48:8+24:8= 6+3= 9
(49+21):7 = 49:7+21:7= 7+3= 10

c)(36+45):9= 36:9+45:9= 4+ 5= 9
(48+12):6= 48:6+12:6= 8+2= 10

Answer 2

a)

( 27 + 54 ) : 9 =

27 : 9 + 54 : 9 =

3 + 6 = 9

( 56 + 16 ) : 8 =

56 : 8 + 16 : 8 =

7 + 2 = 9

b)

( 48 + 24 ) : 8 =

48 : 8 + 24 : 8 =

6 + 3 = 9

( 49 + 21 ) : 7 =

49 : 7 + 21 : 7 =

7 + 3 = 10

c)

( 36 + 45 ) : 9 =

36 : 9 + 45 : 9 =

4 + 5 = 9

( 48 + 12 ) : 6 =

48 : 6 + 12 : 6 =

8 + 2 = 10
