(
47) * 3
2 x (3.80)
(34 - 17) X 3
12 - 15 x 5
4 * 5 = 12:23
5 - (13 - 9) =
55:5 + 14 =
17 x 2 - 16 =​

Answer 1

Respuesta:

(47)*3 = 47 x 3 = 141

2x 3'80= 7.6

(34-17) x3 = (17) x 3 = 51

12- 75 = - 63

20 = 0,52 ; 20 - 0.52 =19, 48

5- ( 13-9)= 5- (4) = 1

55:5 +14 = 11+14 = 25

17x 2 - 16 = 34-16 = 18
