calculează pls dau COROANA​

Answer 1

1,(2) × 3,14

12-1/9 ×314/100

11/9 ×314/100

3453/900 (simplificam cu 3)

1151/300=38,3(6)

b)(-5,6) ×0,(6)= (-56/10) × 6/9 ( simplificam 6/9 cu 3)

(-56/10) × 2/3 = -112/30(simplificam cu 2)

-56/15= -3,7(3)

c)

(-1,1) × (-2,(3))

= -11/10 × -23-2/9

-11/10 × 21/9

-231/90(simplificam cu 3)

-77/30=-2,5(6)

d)

3,(2) × ( -1,4(3))

32-3/9 × (-143-14/90)

29/9 × ( -219/90)

-6351/81(simplificam cu 3)

-2117/27=78,(407)
