1. ( 28 x 2) x 3=56 x 168
2. cate kg s-au adus?
100 x 7 = 700 kg
cate kg au ramas?
700 - 278 = 422
3.a + b + c = 195
a = 26
b = 26 x 5 = 130
c = ?
intai facem suma a + b = 26 + 130=156
156 + c = 195
c = 195 - 156 = 39
c = 39
4.a - ( 7 x 7 ) = 7 + 7 x 3
a - 49 = 28
a = 28 + 49
a = 77
5 . cate fructe a primit de fiecare fel?
60 : 10 = 6 gutui
70 : 10 = 7 mure
40 : 10 = 4 pere
Cate fructe a primit un nepot in total?
6 + 7 + 4 =13 + 4 =17 fructe

1. (2x28)x3=168
56x3=168
2. 100 lazi x 7 kg=700 kg struguri
700 kg -278 kg=422 kg ramase
3. a+b+c=195
a=26 b=26x5 b=130
c=?
26+130+ c=195
156+c=195
c=195-156 c=39
26+130+39=195
156+39=195
4. 7X3+7=21+7=28
7x7=49
49+28=77
77-49=28
5. 60 gutui:10=6 gutui fiecare copil
70 mure:10=7 mure fiecare copil
40 pere:10=4 pere fiecare copil
6+7+4=17 fructe fiecare copil
